Let the heavens rejoice, and let the earth be glad; let the sea roar, and the fulness thereof.

King James Translators' Notes

the fulness...: or, all it containeth

Jamieson-Fausset-Brown Bible Commentary

11-13. For which reason the universe is invoked to unite in joy, and even inanimate nature (Ro 8:14-22) is poetically represented as capable of joining in the anthem of praise.

Matthew Henry's Concise Commentary

96:10-13 We are to hope and pray for that time, when Christ shall reign in righteousness over all nations. He shall rule in the hearts of men, by the power of truth, and the Spirit of righteousness. His coming draws nigh; this King, this Judge standeth before the door, but he is not yet come. The Lord will accept the praises of all who seek to promote the kingdom of Christ. The sea can but roar, and how the trees of the wood can show that they rejoice we know not; but He that searches the heart knows what is the mind of the Spirit, and understands the words, the broken language of the weakest. Christ will come to judge the earth, to execute just vengeance on his enemies, and to fulfil his largest promises to his people. What then are we? Would that day be welcome to us? If this be not our case, let us now begin to prepare to meet our God, by seeking the pardon of our sins, and the renewal of our souls to holiness.
