psa 139:2Afar off - Thou knowest what my thoughts will be in such and such circumstances, long before I know it, yea from all eternity.
psa 139:3Compassest - Thou discernest every step I take. It is a metaphor from soldiers besieging their enemies, and setting watches round about them.

psa 139:6I cannot - Apprehend in what manner thou dost so presently know all things.
psa 139:8Hell - If I could hide myself in the lowest parts of the earth.
