זוהר בראשית — דף רמט ע”א

The wisdom of Solomon is his mother, that is the supernal Binah, according to the meaning of 'the words of Lemuel king.' These words of Lemuel are words spoken on behalf of God who is King, this God who is angry every day and El Shadai. Lemuel means Lemo El, which is Bat Sheva. David transmitted to Solomon the secret of the holy Torah, and Solomon received supernal wisdom from his mother. El Shadai is the one who said 'Enough' to His divinity, to fill the children of Israel.
