'Mother's' in the Bible

“You are not to eat any carcass; you may give it to a temporary resident living within your gates, and he may eat it, or you may sell it to a foreigner. For you are a holy people belonging to the Lord your God. You must not boil a young goat in its mother’s milk.

‘The one who sleeps with his sister, whether his father’s daughter or his mother’s daughter is cursed.’And all the people will say, ‘Amen!’
