Isaiah 38:19
The living, the living, he shall praise thee, as I do this day: the father to the children shall make known thy truth.
The living, the living, he shall praise thee, as I do this day,.... Every one of the living, or such who are both corporeally and spiritually alive; and therefore the word is repeated; none but such who are alive in a corporeal sense can praise the Lord in this world; and none but such who are spiritually alive can praise him aright, and such do under a true sense of the greatness of his mercies, and of their own unworthiness; and such a one was Hezekiah; for the words may be rendered, "as I am this day {x}"; that is, alive in both the above senses; and so did he praise God, in such a spiritual manner, even on the day he committed this to writing, and was now in the temple offering up this thanksgiving:
the father to the children shall make known thy truth: not meaning himself, for at this time he had no children; though, no doubt, when he had any, as he afterwards had, particularly Manasseh, he took care to acquaint him with the truth and faithfulness of God in the fulfilling of his promises to him; and which every religious parent would do, and so transmit the memory thereof to future ages.
