Charles H. Spurgeon on Psalms 140:10

Let burning coals full upon them, etc. An imprecation which (with the similar previous one, Ps 9:6, etc.) is a prophecy; and one which, while it has had no fulfilment in the case of David's enemies, or any persecutors of the church in times past, brings again vividly before the mind the fiery judgment of the Lord's coming, and the awful sentence already pronounced against "the beast and false prophet", the leaders of the confederation of the kings of the earth and their armies, then "gathered together to make war against him" —"these were cast alive into the lake of fire burning with brimstone": Re 19:19-20. So before, Ps 55:15 63:9. —William De Burgh.
