Albert Barnes Commentary Psalms 119:15

"I will meditate on thy precepts, And have respect unto thy ways." — Psalms 119:15 (ASV)

I will meditate in thy precepts - I will think of them; I will find my happiness in them. See the notes at Psalms 1:2.

And have respect unto thy ways - And look to your ways - your commands. I continually regard them, or refer to them in my mind as the guide of my life. See the notes at Psalms 119:6.
