הָב֣וּ לַֽ֭יהוָה כְּב֣וֹד שְׁמ֑וֹ הִשְׁתַּחֲו֥וּ לַ֝יהוָ֗ה בְּהַדְרַת־קֹֽדֶשׁ׃
Ascribe unto the LORD the glory due unto His name; Worship the LORD in the beauty of holiness.

the glory due His name This is the blessing of the sanctity of the Name [the third blessing of the Amidah]. In this psalm, there are eighteen mentions of God’s name, and corresponding to them, they instituted eighteen blessings.
