Galatians 4:21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31
Galatians 4:22 ESV
For it is written that Abraham had two sons, one by a slave woman and one by a free woman.
Galatians 4:23 ESV
But the son of the slave was born according to the flesh, while the son of the free woman was born through promise.
Galatians 4:24 ESV
Now this may be interpreted allegorically: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar.
Galatians 4:25 ESV
Now Hagar is Mount Sinai in Arabia; she corresponds to the present Jerusalem, for she is in slavery with her children.
Galatians 4:29 ESV
But just as at that time he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now.
Galatians 4:30 ESV
But what does the Scripture say? “Cast out the slave woman and her son, for the son of the slave woman shall not inherit with the son of the free woman.”
