Psalms 93:5 - Exposition

Thy testimonies are very sure. God's "testimonies" are his commandments, considered as witnesses to man of his nature and his will respecting them. They are "very sure," i.e. firm and unalterable, partaking of his unchangeability ( James 1:17 ). Holiness becometh thine house, O Lord, forever. "Holiness" here seems to mean "sanctity," "inviolability". This is a tacit appeal to God to keep his temple free from all profanation and pollution in the future. The psalmist does not really ask that it shall continue inviolate "forever," but "to length of days," i.e. for an ample period.
