Adam Clarke, on Neh 6:18

“For there were many in Judea sworn to him, because he was the son in law of Sechenias the son of Area, and Johanan his son had taken to wife the daughter of Mosollam the son of Barachias.”

“He was the son-in-law of Shechaniah - Previously to the coming of Nehemiah, the Jews seemed to be fast intermixing with the heathen, by intermarriages with Ashdodites, Ammonites, and Moabites; see Neh 13:23. Ezra had many evils of this kind to redress, (Ezr 9:3, etc.), chiefly among the common people, though there were both chiefs and priests in that trespass. But here we find the heathen and Jewish nobles interlinked; and the latter were so far imbued with the spirit of idolatry, that they forgot God, his service, their brethren, and their own souls.”
