Saul zaś oddał był Michalę, córkę swoją, żonę Dawida, Paltiemu, synowi Laisza z Gallim.

Similarly, you can say (2 Sam. 21:8), "And the five sons of Michal daughter of Saul that she bore to Adriel [son of Barzilai] the Mecholatite, etc." Here we find that [Saul] gave Michal to Adriel the Mecholatite. But did he not give her, rather, to Palti son of Laish from Gallim? For it says (1 Sam. 25:44), "And Saul gave Michal his daughter, the wife of David, to Palti son of Laish." Rather, the marriage of Michal is juxtaposed to the marriage of Merav (see 1 Sam. 18:19). Just as the marriage of Merav [was consummated] through sin, so too the marriage of Michal to Palti ben Laish [was consummated] through sin.
