John Gill Commentary Psalms 44:14

"Thou makest us a byword among the nations, A shaking of the head among the peoples." — Psalms 44:14 (ASV)

You make us a byword among the Heathen Among the Papists, as the Jews were among the Gentiles, (Deuteronomy 28:37) (Jeremiah 24:9) ; calling them schismatics, heretics, fanatics, and what not?

a shaking of the head among the people ; by way of indignation, scorn, and contempt; see (Psalms 22:7) (109:25) .
