1 To the chief musician, by David, a psalm. O Lord! thou hast searched me through, and thou knowest me.

2 Thou indeed knowest my sitting down and my rising up, thou understandest my thinking while yet afar off.

3 My walking and my lying down hast thou limited, and with all my ways art thou acquainted.

4 For, while there is not a word on my tongue, lo, thou, O Lord, knowest it entirely.
