Because that Abraham hearkened to My voice, and kept My charge, My commandments, My statutes, and My laws. Gen 26:5
The primitive root
Strong’s H4687, mitsvah, a concrete noun meaning, “commandment;” from Strong’s H6680 צוה tsavah, a primitive root meaning, “to set up, to constitute, to appoint.” The ancient pictographs are tsadey + vav + hey.
tsadey צ, ץ = the trail, thus a man concealed, journey, chase, hunt
vav ו = the tent peg, thus add, secure, hook
hey ה = man with upraised arms, thus look, reveal, wonder, worship, breath
The story the ancient pictographs are telling is of the path (tsadey) made sure (vav) by revelation (hey). A sure path, made more sure since it is the one revealed to man by God.
