Psalms 79:9

עָזְרֵנוּ אֱלֹקי יִשְׁעֵנוּ עַל דְּבַר כְּבוֹד שְׁמֶךָ וְהַצִּילֵנוּ וְכַפֵּר עַל חַטֹּאתֵינוּ לְמַעַן שְׁמֶךָ

Help us, G-d of our salvation, for the sake of the glory of Your Name, and deliver us and forgive our sins for Your Name's sake.

This verse is the last line of the prayer Tachanun. Metzudas David explains “the sake of the glory of Your Name” to mean so that G-d’s Name should not be disgraced. “For Your Name’s sake” means to demonstrate that He is gracious and kind.
