Give unto the LORD the glory due unto his name; worship the LORD in the beauty of holiness. The glory due unto his name - Rather, the glory of his name. His name is Mercy; his nature is love. Ascribe mercy, love, power, and wisdom to him. All these are implied in the name Jehovah.
In the beauty of holiness - בהדרת קדש behadrath kodesh, "the beautiful garments of holiness." Let the priests and Levites put on their best and cleanest apparel; and let the whole service be conducted in such a way as to be no dishonor to the Divine Majesty. The Vulgate and others read, In the palace of his holiness. Let all go to the temple, and return thanks to God for their preservation during this dreadful storm. See on Psalms 29:9 (note).
