Charles H. Spurgeon on Psalms 78:64

Their widows made no lamentation. The meaning is, either 1. That being overwhelmed with sorrow they could not weep; or, 2. That being in captivity amongst the Philistines they were not suffered to lament the death of their husbands; or, 3. That dying with grief they lived not to make any lamentations for them at their funerals; or, 4. That they were so taken up and oppressed with their own miseries, and especially with the miseries of the church and people of God in general, that they had not leisure to bewail their husbands; of both which last we have a clear instance in the wife of Phinehas in particular, 1Sa 4:19-20, who dying, made no mention of her husband.
