What is the meaning of "v'Yesh Mehem Nashim va'Yasimu Banim"?

Rashi: Some of them had children from their Nochri wives - they expelled everyone, the wives and the children.
2.
Ibn Ezra: Perhaps "va'Yasimu" means that they put their children l'Fi 1 Roshei ha'Avos, to take counsel if they should expel them or draw them close.
3.
Malbim: "Nas'u" above applies also here, as if it says v'Yesh Mehem Nas'u Nashim. It says va'Yasimu, and not v'Yaldu, for a Nochris' son is like her (he is not attributed to his father).
