'Sons of Men' in the Bible

I gathered to me also silver and gold, and the wealth of kings, and the provinces: I made to me men singing and women singing, and the delights of the sons of men, a wife and mistresses.

For also man knew not his time: as the fishes being laid hold of in an evil net, and as the birds laid hold of in the snare, as they, the sons of men being snared for an evil time, as it will fall upon them suddenly.
