And now am I their song - See Job 17:6; compare Psalms 69:12, “I was the song of the drunkards;” Lamentations 3:14, “I was a derision to all my people, and their song all the day.” The sense is, that they made Job and his calamities the subject of low jesting, and treated him with contempt. His name and sufferings would be introduced into their scurrilous songs to give them pith and point, and to show how much they despised him now.
Yea, I am their by-word - See the notes at Job 17:6.
