Albert Barnes Commentary Psalms 119:168

"I have observed thy precepts and thy testimonies; For all my ways are before thee. TAV." — Psalms 119:168 (ASV)

I have kept thy precepts and thy testimonies — This is an appeal which is several times made in the psalm; not with boasting, but as indicating the tenor and purpose of his life. Every man ought to be able to make such an appeal.

For all my ways are before thee — You have seen my manner of life, and I may appeal to you in proof that I have thus kept your law. No one can lay claim to entire perfection, but there is many a man who, while conscious of much imperfection, and many shortcomings, can appeal to God for the truth of the statement that his great aim of life has been to keep his commandments.
