Charles H. Spurgeon on Psalms 44:14

Thou makest us a byword; literally, for a similitude, (lvm) stands here, as in the original passage De 28:37, in the common signification, similitude. The misery of Israel is so great, that people would figuratively call a miserable man a Jew, just as liars were called Cretans; wretched slaves, Sardians. So far as the people from being now "blessed of the Lord" in whom according to the promise, all the heathen are to be blessed. E. W. Hengstenberg.
