Adam Clarke on Psalms 137:4

How shall we sing the Lord's song - איך נשיר eich! nashir; O, we sing! Who does not hear the deep sigh in the strongly guttural sound of the original איך eich! wrung, as it were, from the bottom of the heart? Can We, in this state of slavery, - We, exiles, from our country, We, stripped of all our property, - We, reduced to contempt by our strong enemy, - We, deprived of our religious privileges, - We, insulted by our oppressors, - We, in the land of heathens, - We sing, or be mirthful in these circumstances? No: God does not expect it; man should not wish it; and it is base in our enemies to require it.
