'Circumcised' in the Bible

but every man's servant who is bought for money, when you have circumcised him, then shall he eat of it.

When a stranger shall live as a foreigner with you, and will keep the Passover to Yahweh, let all his males be circumcised, and then let him come near and keep it; and he shall be as one who is born in the land: but no uncircumcised person shall eat of it.
