Their names seem to indicate kinship to the Semitic Language. Jacum may be related to the Hebrew Jakim (24:12), signifying one who is raised up by the Lord; it evidently comes from the verb, kum, to stand up. It may also be related to khamamu, which is said to mean to hold, to fix, to grasp, and in Babylonian to fix the laws, to lead, to govern (H. F. Lutz, Kingship in Babylonia, Syria, and Egypt; American Anthropologist, October and December, 1924).
Gilgah may be a variant of Gilgal, which means a wheel, or a circle. It was the place where the Israelites made their first camp in Palestine, after having crossed the Jordan and occupied Jericho. It was there that they set up twelve stones, possibly in a circle, forming a stonehenge in memory of that great event in Israelitish history (2 Kings 16:10-12), meaning the light of the Lord.
