31:27 Days would come when the Lord would fill the Promised Land with people and animals once again. The land had become desolate because of the exiles.
31:28 As Yahweh directed the breaking down of His nation, so He would oversee its building up.
31:29-30 In that time of future blessing people would no longer repeat a popular proverb that said that the children were bearing the consequences of their fathers' sins. This proverb expressed a popular misconception (cf. Deut. 24:16; Ezek. 18:25). It blamed present trouble on past ancestors inordinately. In that day everyone would bear the consequences of his own actions. Justice would be obvious then whereas at present it did not seem to be operating. Whereas people do suffer for the sins of their ancestors to a limited extent (corporate responsibility), they much more consistently suffer for their own sins (individual responsibility).
