Solomon, as a Torah scholar,
converted Pharaoh’s daughter (as well as each of his subsequent foreign wives)
before he married her. However, since these foreign-born wives were not
converted with the prior consent of the Sanhedrin, Scripture censures Solomon
for marrying them. Moreover, in the end, the Sanhedrin’s fears proved valid
(see 11:1-10), as these wives never fully abandoned their idol worship (Rambam).
