'Offspring' in the Bible

For it is clear that He does not reach out to help angels, but to help Abraham’s offspring.

By faith even Sarah herself, when she was unable to have children, received power to conceive offspring, even though she was past the age, since she considered that the One who had promised was faithful.

Therefore from one man—in fact, from one as good as dead—came offspring as numerous as the stars of heaven and as innumerable as the grains of sand by the seashore.

Now if you are exempt from correction and without discipline, in which all [of God’s children] share, then you are illegitimate children and not sons [at all].
