Behold, I have longed after thy precepts,.... After a greater degree of knowledge of them, and an opportunity of hearing them explained and enforced, and of yielding obedience to them; see Psa 119:7; quicken me in thy righteousness: in the way of righteousness, according to the word of righteousness, the Gospel, and with the righteousness of Christ revealed in it; and which is unto life, and quickens and comforts the heart, and from whence abundance of peace and joy flows.
