'Seed' in the Bible

And they brought the head of Ish-bosheth unto David to Hebron, and said to the king, Behold, the head of Ish-bosheth, the son of Saul, thine enemy, who sought thy life; and Jehovah hath avenged my lord the king this day of Saul, and of his seed.

When thy days are fulfilled, and thou shalt sleep with thy fathers, I will set up thy seed after thee, that shall proceed out of thy bowels, and I will establish his kingdom.

Great deliverance giveth he to his king, And showeth lovingkindness to his anointed, To David and to his seed, for evermore.
