Isaiah 48:17

Thus saith the LORD, thy Redeemer, the Holy One of Israel; I [am] the LORD thy God which teacheth thee to profit, which leadeth thee by the way [that] thou shouldest go.

Ver. 17. I am the Lord thy God which teacheth thee to profit.] And do therefore so oft call upon thee to hear me, not for any benefit to myself, but to thee alone. And the truth is, in all the commandments of God, if they were open to us, if we did see the ground of them, we should see there were so much reason for them, and so much good to be got by them, that if God did not command them, yet it would be best for us to practise them.

Which leadeth thee by the way that thou shouldest go.] Heb., Making thee to tread in the way thou shalt walk, carefully choosing thy steps for thee, and setting thy foot right: thus "he led Joseph like a sheep," Psa 80:1 and "Israel through the deep, as a horse in the wilderness, that they should not stumble." Isa 63:13 Thrice happy are the saints in such a guide. "The steps of a good man are ordered by the Lord, and he delighteth in his way." Psa 37:23
