'Sons' in the Bible

And he saith, 'These are the two sons of the oil, who are standing by the Lord of the whole earth.'

When I have bent Judah for me, filled the bow with Ephraim, and raised up thy sons, O Zion, against thy sons, O Greece, and made thee as the sword of a mighty man.

And Ephraim hath been as a hero, And rejoiced hath their heart as wine, And their sons see, and they have rejoiced, Rejoice doth their heart in Jehovah.

And I sow them among peoples, And in far-off places they remember Me, And they have lived with their sons, And they have turned back.
