Charles Ellicott Commentary Galatians 1:5

"to whom [be] the glory for ever and ever. Amen." — Galatians 1:5 (ASV)

Glory.—Perhaps, properly, the glory—that is, the divine glory: that pre-eminent glory with which no other can compare.

If this is the case, then it would be better to supply “is” rather than “be.” His own peculiar glory does belong to God, and therefore the Christian ascribes it to Him as that which is already His; he does not pray for it as something unfulfilled, as, for example, he prays for the coming of God’s kingdom.

In the insertion of this brief doxology, the mind of the Apostle obeys an involuntary impulse of reverential awe. For a similar ascription in the same parenthetic form, compare Romans 9:5.

For ever and ever.—Literally, for ages of ages, a Hebraizing expression for infinite time. Commonly, time was divided only into two great world-periods; but the second is, as it were, multiplied indefinitely—“for all possible ages.”
