Matthew Henry Presbyterian

Here is, 1. A great duty enjoined, particularly to those that are the parents and instructors of children, in order to the propagating of wisdom, that it may not die with them: Train up children in that age of vanity, to keep them from the sins and snares of it, in that learning age, to prepare them for what they are designed for.

John Gill Reformed Baptist

Train up a child in the way he should go,.... As Abraham trained up his children, and those born in his house, in the way of the Lord, in the paths of justice and judgment; which are the ways in which they should go, and which will be to their profit and advantage; see Gen 14:14; and which is the duty of parents and masters...

Jamieson-Fausset-Brown Reformed

Train--initiate, or early instruct. the way--literally, "his way," that selected for him in which he should go; for early training secures habitual walking in it.
