Barnes' Notes
The voice of rejoicing and salvation - Rejoicing for salvation; song, praise, thanksgiving. Luther renders this beautifully; "They sing with joy for victory in the houses of the righteous."
Is in the tabernacles of the righteous - The tents of the righteous; their dwellings. That is,
(a) it is a fact that the voice of joy and rejoicing is there;
(b) it is appropriate that it should be so, or that a righteous family should be happy - the dwelling-place of praise;
(c) God will add to the happiness of the righteous, or will make their habitation happy, peaceful, blessed.
There is nothing that diffuses so much happiness through a family as religion; there is no joy like that when a member of a family is converted; there is no place on earth more happy than that where a family bows before God with the feeling that all are children of God and heirs of salvation.
The right hand of the Lord doeth valiantly - Hebrew "Doeth strength." That is, God does great things, laying the foundation for joy and praise.
