It is thought that this psalm was written by David, at the great occasion of the bringing up of the Ark to Zion. It was great because David understood that the Ark was typical of Christ, the Messiah to come. There is, beyond the immediate fulfilment, an anticipation of Christ coming to His church, which Zion represents.
Throughout the psalm there is a praising ascription of the glory of Christ and His greatness. We are encouraged to follow suit by David, urging, “Give unto the Lord the glory due.” And His promises shall not fail, for Christ shall come and judge the world with the balances of righteousness and truth. It is interesting to note that an old rendering of v. 10, reads, “The Lord reigneth from the tree,” which beautifully expresses that Calvary’s cross is really a Throne.
