judges 1:16 And the children of the Kenite, Moses' father in law, went up out of the city of palm trees with the children of Judah into the wilderness of Judah, which lieth in the south of Arad; and they went and dwelt among the people. - Free Bible Online

      16. the children of the Kenite, Moses' father-in-law, went up out of the city of palm trees with the children of Judah--called "the Kenite," as probably descended from the people of that name (Nu 24:21, 22). If he might not himself, his posterity did accept the invitation of Moses (Nu 10:32) to accompany the Israelites to Canaan. Their first encampment was in the "city of palm trees"--not Jericho, of course, which was utterly destroyed, but the surrounding district, perhaps En-gedi, in early times called Hazezon-tamar (Ge 14:7), from the palm-grove which sheltered it. Thence they removed for some unknown cause, and associating themselves with Judah, joined in an expedition against Arad, in the southern part of Canaan (Nu 21:1). On the conquest of that district, some of this pastoral people pitched their tents there, while others migrated to the north (Jud 4:17).
