Tafsiran 1 Samuel 1:8: Rashi, Metzudat David & Radak

Am I not better to you. Don't I love you more dearly.

And why is your heart grieved: Why should your heart be broken from grieving for the lack of children?

Am I not: It is like the Targum [Yonatan], "Is not my wish better to you" - meaning to say, "Is not my wish towards you and my love for you better to you than ten sons?" But some explain, "Am I not better to you than I am to the ten sons I have from Peninah" - meaning to say, I love you more than I love my sons. And he said this because Peninah had ten sons. But according to our explanation, the reason for [the word], "ten," is by way of a general (figurative) count - as in (Leviticus 26:26), "and ten women will bake"; "than ten rulers" (Ecclesiastes 7:19); "seven times like your sins" (Leviticus 26:21); "seven times does a righteous one fall" (Proverbs 24:16); and that which is similar to them.

Than ten sons. That Penina has borne to me.¹³Others interpret that Elkonoh did not mean literally ten sons and with reference to Penina, but rather he was expressing his love to Chana and happened to pick that number , as we find the same number in Vayikra 26:26.—Radak
