The righteousness of thy testimonies [is] everlasting
Or, "for ever" F2. The righteousness which they require, or which they publish; the righteousness revealed in the Gospel, which is the righteousness of Christ; (See Gill on Psalms 119:142);
give me understanding, and I shall live;
an understanding of the testimonies of the Lord, of the word of God, the law of God, and Gospel of Christ; an understanding of divine and spiritual things; a clearer and larger understanding of them, which is the gift of God; both that itself at first, and an increase of it here prayed for, the end, issue, and effect of which is life. Such live spiritually, and by faith; they live cheerfully and comfortably, and "for ever", as Aben Ezra and Kimchi repeat from the former clause: for "this is life eternal know the only true God and Jesus Christ"; or to have spiritual understanding of them, and of those things which relate to spiritual peace and comfort here, and eternal happiness hereafter, ( John 17:3 ) .
