'Seed' in the Bible

And these were they that went up from Tel-melah, Tel-harsha, Cherub, Addan, and Immer; but they could not show their fathers houses, and their seed, whether they were of Israel:

For they have taken of their daughters for themselves and for their sons, so that the holy seed have mingled themselves with the peoples of the lands: yea, the hand of the princes and rulers hath been chief in this trespass.
