'Seed' in the Bible

concerning his Son, who was born of the seed of David according to the flesh,

For not through the law was the promise to Abraham or to his seed that he should be heir of the world, but through the righteousness of faith.

For this cause it is of faith, that it may be according to grace; to the end that the promise may be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham, who is the father of us all

Who in hope believed against hope, to the end that he might become a father of many nations, according to that which had been spoken, So shall thy seed be.

neither, because they are Abraham's seed, are they all children: but, In Isaac shall thy seed be called.

That is, it is not the children of the flesh that are children of God; but the children of the promise are reckoned for a seed.

And, as Isaiah hath said before, Except the Lord of Sabaoth had left us a seed, We had become as Sodom, and had been made like unto Gomorrah.

I say then, Did God cast off his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin.
