Psalms 80:5

5Thou hast fed us with bread of tears, etc. By these forms of expression, they depict the greatness of their grief, and the long continuance of their calamities; as if they had said, We are so filled with sorrow, that we can contain no more. (388) They add, in the following verse that they were made a strife to their neighbors This admits of being explained in two ways. It means either that their neighbors had taken up a quarrel against them; or that, having obtained the victory over them, they were contending about the spoil, as is usually the case in such circumstances, each being eager to drag it to himself. The former interpretation, however seems to be the more suitable. The people complain that, whereas neighborhood ought to be a bond of mutual goodwill, they had as many enemies as neighbors. To the same purpose is their language in the second clause, They laugh at us among themselves; that is to say, They talk among themselves by way of sport and mockery at our adversities. To encourage and stir themselves up to repentance, they ascribe all this to the judgment of God, in whose power it is to bend the hearts of men. Since we are all at this day chargeable with the same sins, it is not surprising that our condition is in no degree better than was theirs. But the Holy Spirit having inspired the prophet to write this form of prayer for a people who felt their condition to be almost desperate, it serves to inspire us with hope and boldness, and to prevent us from giving up the exercise of prayer, under a consciousness of the greatness of our guilt. The seventh verse is a repetition of the third; and this repetition is undoubtedly intended as a means of surmounting every obstacle. God did not here intend to endite for his people a vain repetition of words: his object was to encourage them, when bowed down under the load of their calamities, boldly to rise up, heavy though the load might be. This ground of support was often presented to them; and it is repeated the third time in the concluding verse of the psalm.
