'Instead' in the Bible

And Absalom set Amasa over the host instead of Joab; which Amasa was the son of a man whose name was Jithra the Israelite, that went in to Abigail the daughter of Nahash, sister to Zeruiah, Joab's mother.

And say to Amasa, Art thou not my bone and my flesh? God do so to me and more also, if thou be not captain of the host before me continually instead of Joab.
