And this have ye done again— This also you have done; you have covered the altar of the Lord with tears, with weeping, and with groanings; so that no respect is now had to your offering, nor is any thing accepted from your hand. The priests not only had married strange wives, but also divorced those of their own country whom they had married; with whose tears the altar was imbrued, when these wives offered up their sacrifices to God, entreating him to give their husbands a better mind; whom God heard so effectually, that he would not accept the sacrifices of their husbands, on account of the tears and just complaints of their wives. Houbigant.
