'Seed' in the Bible

and bring in the head of Ish-Bosheth unto David in Hebron, and say unto the king, 'Lo, the head of Ish-Bosheth, son of Saul, thine enemy, who sought thy life; and Jehovah doth give to my lord the king vengeance this day, of Saul and of his seed.'

'When thy days are full, and thou hast lain with thy fathers, then I have raised up thy seed after thee which goeth out from thy bowels, and have established his kingdom;

Magnifying the salvations of His king, And doing loving-kindness to His anointed, To David, and to his seed -- unto the age!'
