22 For it is written that Abraham had two sons, one by the slave woman and the other by the free woman.

Darby

22 For it is written that Abraham had two sons; one of the maid servant^D8567, and one of the free woman.

Darby Bible Notes

servant - Or 'bondmaid,' paidiske (as Acts 12.13). Though in practice the word amounted to the same as a bondmaid, yet the Greek root is essentially different from that of doulos, a bondman, or slave.

KJV

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