תּלמוד אויף שמואל א 25:41

Rebbi Abbahu said: It happened that Rebbi Eliezer’s mother was pushing him to marry his sister’s daughter. He said to [the girl]: go and get married, go and get married, until she said to him: Here I am your slave girl to wash the feet of my master’s servants⁴⁹A slightly garbled version of Abigail’s speech, 1S. 25:41.. Even though he married her, he did not sleep with her until she had grown two pubic hairs⁵⁰Since for him, sleeping with an underage girl is tantamount to seducing her, even in a marriage..
