וַיִּתֵּ֤ן לָבָן֙ לְרָחֵ֣ל בִּתּ֔וֹ אֶת־בִּלְהָ֖ה שִׁפְחָת֑וֹ לָ֖הּ לְשִׁפְחָֽה׃
At ibinigay ni Laban si Bilha na kanyang aliping babae kay Raquel na kanyang anak na babae, upang maging kanyang alipin.
Or HaChaim
לה לשפחה. as a maidservant for her. The Torah was careful to add the word לה, as I have already explained in connection with verse 24.
Or HaChaim
Alternatively, Laban made a condition that Jacob should not have any claim on Bilhah; we find in chapter 22 of Maimonides' Hilchot Ishut that if someone gives a wife a gift with the proviso that her husband should not have any claim on that gift, then the husband is not permitted to enjoy the "fruits" of such a gift (in this case Bilhah's labour, etc,). It is a principle of our sages to follow a line of exegesis which puts Laban in a bad light.
