Isaiah 48:11

For mine own sake, [even] for mine own sake, will I do [it]: for how should [my name] be polluted? and I will not give my glory unto another.

Ver. 11. For mine own sake, even for mine own sake.] This is oft repeated, that it may once be well observed. Bene cavet Spiritus Sanctus ubique in Scripturis ne nostris operibus salutem tribuamus; it is Oecolampadius's note upon the first verse of this chapter, i.e., the Holy Ghost doth everywhere in Scripture take course that we ascribe not our safety to our own works. See on Isaiah 43:13 .

For how should my name be polluted?] As it will be by the blasphemous heathens, who else will say that their gods are fortiores et faventiores, more powerful and more merciful than the God of the Hebrews. Thus the Turks at this day, when they have beaten the Christians, cry up their Mohammed as mightier than Christ.

And I will not give my glory to another.] Press this in prayer: it is an excellent argument. Exo 32:12 Jos 7:9 Psalms 79:9,10 ; Psa 115:1-2 The saints, after all other arguments used, hunc quasi arietem admovent, mind God of his glory engaged, and then doubt not to prevail with him.
