Albert Barnes Commentary Psalms 119:161

"Princes have persecuted me without a cause; But my heart standeth in awe of thy words." — Psalms 119:161 (ASV)

Princes have persecuted me without a cause - This begins a new division of the psalm, indicated by the Hebrew letter Schin (שׂ ś — and שׁ sh) - corresponding to our “s,” or “sh.” On the meaning of the expression here, see Psalm 119:23, note; Psalms 119:76, note.

But my heart standeth in awe of thy word - I still reverence your word. I am not deterred from keeping your law by any threats or intimidations. This is in accordance with the uniform statements in the psalm, that nothing deterred him from manifesting his adherence to the law of God.
