1 Chronicles 2:18

Not that Caleb, Numbers 13:6, for he was the son of Jephunneh, of whom he speaks, 1 Chronicles 4:15; but another Caleb. Her sons, i.e. the sons, either, 1. Of Jerioth, she being last mentioned; or rather,

2. Of Azubah, who is by way of distinction called his wife, when Jerioth probably was only his concubine, and, as it may seem, barren; and therefore upon Azubah's death he married another wife, 1 Chronicles 2:19. And those other sons of this Caleb, mentioned below, 1 Chronicles 2:42, are his sons by some other wife distinct from all these.
