Commentary for Proverbs 31:2

What, my son What is this that you have done and told that you are my son, and [you did] not [tell] that you are the son of your father. Everybody knows that your father was completely righteous, and if you are wicked, they will say, “His mother made him that way.”

the son of my womb All your father’s wives, as soon as they conceived, would not return for marital relations, but I pushed and entered in order to have a son well-formed and of strong vitality, because marital relations are beneficial during the last six months.

and what, the son of my vows? All your father’s wives would vow that they would have a son fit for the throne, but I vowed that I would have a son bright in Torah.
