Charles H. Spurgeon on Psalms 123:4

Exceedingly filled, or perhaps, "has long been filled." (Comp. Ps 120:6). This expression, together with the earnestness of the repeated prayer, "Be gracious unto us", shows that the "scorn" and "contempt" have long pressed upon the people, and their faith has accordingly been exposed to a severe trial. The more remarkable is the entire absence of anything like impatience in the language of the psalm. —J.J. Stewart Perowne.
