1 Chronicles 2:46

And Ephah Caleb's concubine bare Haran, and Moza, and Gazez,
&c.] An half-wife, or secondary wife; for though this man seems not to have had more wives than one at a time, yet he had concubines with them; we read of another after this, if not a third: and Haran begat Gazez;
whom he so named after his brother.
