Adam Clarke on Psalms 10:14

Thou hast seen it - Nothing can escape thy notice. Thou hast not forgotten thy justice, though judgment is not speedily executed on an evil work. But thou wilt requite it with thy hand. By thy power thou wilt cast down and destroy the wicked.

The poor committeth himself unto thee - To thee he has given up his body, his soul, and his cause; with the full conviction that thou who art the helper of fatherless, will not forget him.
