Psalm 71:15

15 My mouth shall tell thy rightfulness; all day thine health. For I knew not (by) literature, that is, by man's teaching, but by God's revelation, (My mouth shall tell out thy righteousness; and thy salvation, or thy deliverance, all day long. For I know not by literature, that is, by man's teaching, or by reading and study, but by the revelation of God.)

Psalm 71:15 Meaning and Commentary

Psalms 71:15

My mouth shall show forth thy righteousness
Both his punitive justice in taking vengeance on his enemies, agreeably to the above imprecations; and his faithfulness in the performance of promises of good things unto him; as also his essential righteousness displayed and glorified in the redemption that is by Christ; and particularly the righteousness of Christ, accepted of God, and imputed by him; which the psalmist with his mouth declared his faith in, expressed his joy at, and set forth in a strong manner the glory and excellency of it, and determined to make mention of it, and of that only, as in ( Psalms 71:16 ) ;

[and] thy salvation all the day;
both temporal and eternal; the glory of both, and praise for the same;

for I know not the numbers [thereof];
of that righteousness and salvation, the numerous blessings which are contained in them; see ( Psalms 40:5 ) ; or "though I know not the numbers of them" ^F3; though he could not fully declare the glories and excellencies of the righteousness and salvation of God, and the numerous mercies and rich grace included in them; yet he would attempt to set them forth in the best way he could, though in a feeble and imperfect manner.

Psalm 71:15 In-Context

13 Men that backbite my soul, be shamed, and fail they; and be they covered with reproof and shame, that seek evils to me. (Let those who backbite me be shamed, and fail they; let those who seek evil for me, be covered with reproach and shame.)

14 But I shall hope ever[more]; and I shall add to ever over all thy praising. (But I shall have hope in thee forevermore; and I shall praise thee more and more.)

15 My mouth shall tell thy rightfulness; all day thine health. For I knew not (by) literature, that is, by man's teaching, but by God's revelation, (My mouth shall tell out thy righteousness; and thy salvation, or thy deliverance, all day long. For I know not by literature, that is, by man's teaching, or by reading and study, but by the revelation of God.)

16 I shall enter into the powers of the Lord; Lord, I shall bethink on thy rightfulness alone. (I shall walk in the Lord's strength; I shall tell out thy righteousness, thine alone.)

17 God, thou hast taught me from my youth, and till to now; I shall tell out thy marvels. (God, thou hast taught me from my youth; and I have told out all thy marvellous deeds.)
