'Heir' in the Bible

"But the vine-dressers, when they saw the son, said to one another, "'Here is the heir: come, let us kill him and get his inheritance.'

"But those men--the vine-dressers--said to one another, "'Here is the heir: come, let us kill him, and then the property will one day be ours.'

"But when the vine-dressers saw him, they discussed the matter with one another, and said, "'This is the heir: let us kill him, that the inheritance may be ours.'

Now I say that so long as an heir is a child, he in no respect differs from a slave, although he is the owner of everything,

Therefore you are no longer a slave, but a son; and if a son, then an heir also through God's own act.

Through faith Noah, being divinely taught about things as yet unseen, reverently gave heed and built an ark for the safety of his family, and by this act he condemned the world, and became an heir of the righteousness which depends on faith.
