Galatians 4:28-30

New Catholic Bible

²⁸Now you, brethren, are, like Isaac, the children of the promise. ²⁹But just as in those days the child who was born through the flesh persecuted the child who was born through the Spirit, so is it now also. ³⁰However, what does Scripture say?

“Drive out the slave woman and her son!
For the son of the slave woman shall not share the inheritance
with the son of the free woman.”
