So I returned, and considered all the oppressions that are done under the sun: and behold the tears of such as were oppressed, and they had no comforter; and on the side of their oppressors there was power; but they had no comforter.
So I returned - namely, to the thought set forth in Ecclesiastes 3:16; Job 35:9.
On the side of their oppressors (there was) power. Maurer, not so well, 'violence.'
They had no comforter. Twice said, to express continued suffering without any to give comfort (Isaiah 53:7).
