Charles Ellicott Commentary Psalms 119:19

"I am a sojourner in the earth: Hide not thy commandments from me." — Psalms 119:19 (ASV)

I am a stranger. —A comparison of Psalm 119:54 with Genesis 47:9 shows that the general transitory condition of life, and not any particular circumstance of the psalmist’s history, is in view.

Human intelligence does not suffice to fathom the will of God. The mortal is a stranger on the earth; both time and strength are lacking to attain knowledge which only Divine wisdom can teach.
