Psalms 137:4 - Joseph Benson’s Commentary on the Old and New Testaments

How shall we sing the Lord's song Those sacred songs which are appropriated to the worship of the true God in his temple, and are appointed by him to be sung only to his honour and in his service; in a strange land When we are banished from our own temple and country, and among those who are strangers and enemies to our God and his worship? How can you imagine that miserable slaves should be disposed to sing songs of joy? Or that we can frame our minds in the land where we are exiles, to sing those songs which recount the mercies of God unto us in our once flourishing country. How, indeed, says Dr. Horne, “could they tune their voices to festive and eucharistic strains, when God, by punishing them for their sins, called to mourning and weeping? But then Israel in Babylon foresaw a day of redemption; and so doth the church in the world; a day when she shall triumph, and her enemies shall lick the dust. No circumstances, therefore, should make us forget her and the promises concerning her.”
