'Sons' in the Bible

Then he said, “These are the two sons of fresh oil [Joshua the high priest and Zerubbabel the prince of Judah] who are standing by the Lord of the whole earth [as His anointed ones].”

For I will bend Judah as My bow,I will fit the bow with Ephraim [as My arrow].And I will stir up your sons, O Zion, against your sons, O Greece,And will make you [Israel] like the sword of a warrior.
