As thou hast said, so must we do - They all resolved to do what Ezra then commanded, they did put away their wives, even those by whom they had children; Ezra 10:44 : this was a great hardship on the women and children. Though by the Jewish laws such marriages were null and void, yet as the women they had taken did not know these laws, their case was deplorable. However, we may take it for granted that each of them received a portion according to the circumstances of their husbands, and that they and their children were not turned away desolate, but had such a provision as their necessities required. Humanity must have dictated this, and no law of God is contrary to humanity. After all, there is some room to doubt whether they did put them finally away, for several years after Nehemiah found Jews that had married wives of Ashdod, Ammon, and Moab; Nehemiah 13:23. And if these were not the same women, we find that the same offense was continued.

Then all the congregation answered and said with a loud voice,.... That they might be heard, and to show that they were willing and ready to comply with what was proposed:
as thou host said, so must we do; being convinced of their sin, they saw it was a duty incumbent on them to put away their strange wives, and that there was a necessity of it, to avert the wrath of God from them.

The whole assembly replied with a loud voice, and therefore with firm resolve: According to thy word it is our duty to do. עלינוּ must not be drawn to what precedes, as in the Vulgate, juxta verbum tuum ad nos, sic fiat, but to what follows, as in Ezra 10:4, Nehemiah 13:13; 2-Samuel 18:11. But - they further remark, Ezra 10:13 - the people are many, - i.e., the assemblage is very large to be able to deal immediately with the several cases; and it is (now) the time of the heavy rains, and there is no power to stand without, - i.e., at the present season we are not able to remain in the open air until the business is discharged; neither is this the work of one day, or of two, for we have transgressed much in this matter, - i.e., one or two days will not suffice to investigate and decide upon all cases, because very many have broken the law in this respect.
