Note, 1. A good heart by the tongue becomes very useful. He that has knowledge is not only to enjoy it, for his own entertainment, but to use it, to use it aright, for the edification of others; and it is the tongue that must make use of it in pious profitable discourse, in giving suitable and seasonable instructions, counsels, and comforts, with all possible expressions of humility and love, and then knowledge is used aright; and to him that has, and thus uses what he has, more shall be given. 2. A wicked heart by the tongue becomes very hurtful; for the mouth of fools belches out foolishness, which is very offensive; and the corrupt communication which proceeds from an evil treasure within (the filthiness, and foolish talking, and jesting) corrupts the good manners of some and debauches them, and grieves the good hearts of others and disturbs them.

The great truths of divinity are of great use to enforce the precepts of morality, and none more than this - That the eye of God is always upon the children of men. 1. An eye to discern all, not only from which nothing can be concealed, but by which every thing is actually inspected, and nothing overlooked or looked slightly upon: The eyes of the Lord are in every place; for he not only sees all from on high (Psa 33:13), but he is every where present. Angels are full of eyes (Rev 4:8), but God is all eye. It denotes not only his omniscience, that he sees all, but his universal providence, that he upholds and governs all. Secret sins, services, and sorrows, are under his eye. 2. An eye to distinguish both persons and actions. He beholds the evil and the good, is displeased with the evil and approves of the good, and will judge men according to the sight of his eyes, Psa 1:6; Psa 11:4. The wicked shall not go unpunished, nor the righteous unrewarded, for God has his eye upon both and knows their true character; this speaks as much comfort to saints as terror to sinners.

Note, 1. A good tongue is healing, healing to wounded consciences by comforting them, to sin-sick souls by convincing them, to peace and love when it is broken by accommodating differences, compromising matters in variance, and reconciling parties at variance; this is the healing of the tongue, which is a tree of life, the leaves of which have a sanative virtue, Rev 22:2. He that knows how to discourse will make the place he lives in a paradise. 2. An evil tongue is wounding (perverseness, passion, falsehood, and filthiness there, are a breach in the spirit); it wounds the conscience of the evil speaker, and occasions either guilt or grief to the hearers, and both are to be reckoned breaches in the spirit. Hard words indeed break no bones, but many a heart has been broken by them.

Hence, 1. Let superiors be admonished to give instruction and reproof to those that are under their charge, as they will answer it in the day of account. They must not only instruct with the light of knowledge, but reprove with the heat of zeal; and both these must be done with the authority and affection of a father, and must be continued, though the desired effect be not immediately perceived. If the instruction be despised, give reproof, and rebuke sharply. It is indeed against the grain with good-humoured men to find fault, and make those about them uneasy; but better so than to suffer them to go on undisturbed in the way to ruin. 2. Let inferiors be admonished, not only to submit to instruction and reproof (even hardships must be submitted to), but to value them as favours and not despise them, to make use of them for their direction, and always to have a regard to them; this will be an evidence that they are wise and a means of making them so; whereas he that slights his good education is a fool and is likely to live and die one.

Note, 1. Where righteousness is riches are, and the comforts of them: In the house of the righteous is much treasure. Religion teaches men to be diligent, temperate, and just, and by these means, ordinarily, the estate is increased. But that is not all: God blesses the habitation of the just, and that blessing makes rich without trouble. Or, if there be not much of this world's goods, yet where there is grace there is true treasure; and those who have but little, if they have a heart to be therewith content, and to enjoy the comfort of that little, it is enough; it is all riches. The righteous perhaps are not themselves enriched, but there is treasure in their house, a blessing in store, which their children after them may reap the benefit of. A wicked worldly man is only for having his belly filled with those treasures, his own sensual appetite gratified (Psa 17:14); but a righteous man's first care is for his soul and then for his seed, to have treasure in his heart and then in his house, which his relations and those about him may have the benefit of. 2. Where wickedness is, though there may be riches, yet there is vexation of spirit with them: In the revenues of the wicked, the great incomes they have, there is trouble; for there is guilt and a curse; there is pride and passion, and envy and contention; and those are troublesome lusts, which rob them of the joy of their revenues and make them troublesome to their neighbours.

This is to the same purport with Pro 15:2, and shows what a blessing a wise man is and what a burden a fool is to those about him. Only here observe further, 1. That we then use knowledge aright when we disperse it, not confine it to a few of our intimates, and grudge it to others who would make as good use of it, but give a portion of this spiritual alms to seven and also to eight, not only be communicative, but diffusive, of this good, with humility and prudence. We must take pains to spread and propagate useful knowledge, must teach some that they may teach others, and so it is dispersed. 2. That it is not only a fault to pour out foolishness, but it is a shame not to disperse knowledge, at least not to drop some wise word or other: The heart of the foolish does not so; it has nothing to disperse that is good, or, if it had, has neither skill nor will to do good with it and therefore is little worth.

Note, 1. God so hates wicked people, whose hearts are malicious and their lives mischievous, that even their sacrifices are an abomination to him. God has sacrifices brought him even by wicked men, to stop the mouth of conscience and to keep up their reputation in the world, as malefactors come to a sanctuary, not because it is a holy place, but because it shelters them from justice; but their sacrifices, though ever so costly, are not accepted of God, because not offered in sincerity nor from a good principle; they dissemble with God, and in their conversations give the lie to their devotions, and for that reason they are an abomination to him, because they are made a cloak for sin, Pro 7:14. See Isa 1:11. 2. God has such a love for upright good people that, though they are not at the expense of a sacrifice (he himself has provided that), their prayer is a delight to him. Praying graces are his own gift, and the work of his own Spirit in them, with which he is well pleased. He not only answers their prayers, but delights in their addresses to him, and in doing them good.

This is a reason of what was said in the foregoing verse. 1. The sacrifices of the wicked are an abomination to God, not for want of some nice points of ceremony, but because their way, the whole course and tenour of their conversation, is wicked, and consequently an abomination to him. Sacrifices for sin were not accepted of those that resolved to go on in sin, and were to the highest degree abominable if intended to obtain a connivance at sin and a permission to go on in it. 2. Therefore the prayer of the upright is his delight, because he is a friend of God, and he loves him who, though he have not yet attained, is following after righteousness, aiming at it and pressing towards it, as St. Paul, Phi 3:13.
