Galatians 4:21 (KJV)

Am I therefore become your enemy, because I tell you the truth?

They zealously affect you, but not well; yea, they would exclude you, that ye might affect them.

But it is good to be zealously affected always in a good thing, and not only when I am present with you.

My little children, of whom I travail in birth again until Christ be formed in you,

I desire to be present with you now, and to change my voice; for I stand in doubt of you.

For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.

But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise.

Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar.

For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children.

But Jerusalem which is above is free, which is the mother of us all.
