Charles Ellicott Commentary Psalms 9:10

"And they that know thy name will put their trust in thee; For thou, Jehovah, hast not forsaken them that seek thee." — Psalms 9:10 (ASV)

They who know. —They who know the name of Jehovah will trust Him, because they know it to be a watchword of strength and protection.

Seek. —From root meaning “to tread” or “frequent a place,” possibly with allusion to frequenting the courts of the Temple.
