וַיַּ֤רְא יְהוָה֙ כִּֽי־שְׂנוּאָ֣ה לֵאָ֔ה וַיִּפְתַּ֖ח אֶת־רַחְמָ֑הּ וְרָחֵ֖ל עֲקָרָֽה׃
И увидел Господь, что Лию ненавидят, и открыл утробу ее; но Рэйчел была бесплодна.
Targum Jonathan on Genesis
And it was revealed before the Lord that Leah was not loved in the sight of Jakob; and He said in His Word that sons should be given her, and that Rahel should be barren.
