To overthrow their seed also among the nations - Margin, as in Hebrew, “to make them fall;” to wit, among the surrounding people. The reference here is to the posterity of those who complained and fell in the wilderness. The result of their rebellion and complaining would not terminate with them. It would extend to their posterity, and the rebellion of the fathers would be remembered in distant generations. The overthrow of the nation, and its captivity in Babylon was thus one of the remote consequences of their rebellion in the wilderness.
And to scatter them in the lands - In foreign lands - as at Babylon. If this psalm was written at the time of the Babylonian captivity, this allusion would be most appropriate. It would remind the nation that its captivity there had its origin in the ancient and long-continued disposition of the people to revolt from God.
