Here is, 1. A charge given to be faithful and constant to our friends, our old friends, to keep up an intimacy with them, and to be ready to do them all the offices that lie in our power. It is good to have a friend, a bosom-friend, whom we can be free with, and with whom we may communicate counsels. It is not necessary that this friend should be a relation, or any way akin to us, though it is happiest when, among those who are so, we find one fit to make a friend of. Peter and Andrew were brethren, so were James and John; yet Solomon frequently distinguishes between a friend and a brother. But it is advisable to choose a friend among our neighbours who live near us, that acquaintance may be kept up and kindnesses the more frequently interchanged. It is good also to have a special respect to those who have been friends to our family: "Thy own friend, especially if he have been thy father's friend, forsake not; fail not both to serve him and to use him, as there is occasion. He is a tried friend; he knows thy affairs; he has a particular concern for thee; therefore be advised by him." It is a duty we owe to our parents, when they are gone, to love their friends and consult with them. Solomon's son undid himself by forsaking the counsel of his father's friends. 2. A good reason given why we should thus value true friendship and be choice of it. (1.) Because of the pleasure of it. There is a great deal of sweetness in conversing and consulting with a cordial friend. It is like ointment and perfume, which are very grateful to the smell, and exhilarate the spirits. It rejoices the heart; the burden of care is made lighter by unbosoming ourselves to our friend, and it is a great satisfaction to us to have his sentiments concerning our affairs. The sweetness of friendship lies not in hearty mirth, and hearty laughter, but in hearty counsel, faithful advice, sincerely given and without flattery, by counsel of the soul (so the word is), counsel which reaches the case, and comes to the heart, counsel about soul-concerns, Psa 66:16. We should reckon that the most pleasant conversation which is about spiritual things, and promotes the prosperity of the soul. (2.) Because of the profit and advantage of it, especially in a day of calamity. We are here advised not to go into a brother's house, not to expect relief from a kinsman merely for kindred-sake, for the obligation of that commonly goes little further than calling cousin and fails when it comes to the trial of a real kindness, but rather to apply ourselves to our neighbours, who are at hand, and will be ready to help us at an exigence. It is wisdom to oblige them by being neighbourly, and we shall have the benefit of it in distress, by finding them so to us, Psa 18:24.

My son, be wise, and make my heart glad,.... That is, show thyself to be a wise man by thy words and actions; endeavour to get a good share of wisdom and knowledge, and make a good use of it, and that will rejoice my heart; as nothing more gladdens the heart of a parent than the wisdom and prudent behaviour of his son; see Pro 10:1;

that I may answer him that reproacheth me; with begetting a foolish son, or a wicked man; or making him such by ill examples; or through neglect of education; or by using too much severity in it.

Adhere to tried friends. The ties of blood may be less reliable than those of genuine friendship.
