Note, 1. It is the way of the upright to avoid sin, and every thing that looks like it and leads towards it; and this is a highway marked out by authority, tracked by many that have gone before us, and in which we meet with many that keep company with us; it is easy to find and safe to be travelled in, like a highway, Isa 35:8. To depart from evil is understanding. 2. It is the care of the upright to preserve their own souls, that they be not polluted with sin, and that by the troubles of the world they may not be put out of the possession of them, especially that they may not perish for ever, Mat 16:26. And it is therefore their care to keep their way, and not turn aside out of it, on either hand, but to press towards perfection. Those that adhere to their duty secure their felicity. Keep thy way and God will keep thee.

The highway of the upright is to depart from evil,.... Upright persons, such who are upright in heart, and walk uprightly; these walk in the highway of holiness, in which men, though fools, shall not err; in the King's highway, the highway of the King of kings; in the plain beaten path of God's commandments; and so shun the bypaths of sin, and abstain from all appearance of it: this is their common constant course of life; they are studiously concerned to walk herein, and take delight in so doing; whereby they escape many evils others fall into;

he that keepeth his way preserveth his soul, that keeps on in his way, the way in which the upright walk; whose eyes look right on, and his eyelids straight before him; who ponders the path of his feet, and turns neither to the right hand nor the left; who walks circumspectly and carefully; observes the road he is in, to keep in it, and not go out of it; such a man preserves his soul from many snares and temptations, troubles, dangers, and evils, which he would be otherwise liable to. Here the Masorites put the word signifying that this is the half or middle of the book.

The highway--A common, plain road represents the habitual course of the righteous in departing from evil.

keepeth--observes.
