Behold, this is the joy of his way, and out of the earth shall others grow.
Behold, is the joy of his way. Bitter irony. The hypocrite boasts of joy. This then is his "joy" at the last.
And out of the earth, х `aapaar (H6083), 'the dust']. "Others" immediately [Hebrew singular, 'always another,' 'acheer (H312)], who take the place of the man thus punished. Not godly men. "God is able of these stones to raise up children to Abraham" (Matthew 3:9). For "the place" of the weeds is among stones, where the gardener would have no plants. But ungodly: a fresh crop of weeds always springs up in the room of those torn up: there is no end of hypocrites on earth (Umbreit). Or, simply, others spring up in his place, and he is not in the least missed.
