Isaiah 42:12

יָשִׂימוּ לַיהוָה כָּבוֹד וּתְהִלָּתוֹ בָּאִיִּים יַגִּידוּ׃

12 Let them give glory to the LORD and let them proclaim his praise in the islands.

יָשִׂימוּ לַיהוָה כָּבוֹד Let them give glory to the LORD, יָשִׂימוּ is another qal jussive, from שִׂים "set, place." The neutral, non-theological meaning of כָּבוֹד is "weight, heaviness," and can be a person's possessions (Genesis 31:1, "all this wealth") or any large "number" of things (Hosea 9:11, "Ephraim: Like a bird, their vastness with fly away"). When used with the divine name, "the glory of the LORD" is a familiar expression, but here the indirect object is not "the LORD," but "to the LORD." The phrase "glory to the LORD" occurs eight times (this is not an Mp notation), six of them in the psalm phrase "ascribe glory to the LORD" (Ps. 29:1; 29:2; 96:7; 96:8; 1 Chr. 16:28; 16:29) and two other places, Isaiah 42:12 and Joshua 7:19, "My son, give glory to the LORD" which is a solemn charge to tell the truth.

וּתְהִלָּתוֹ בָּאִיִּים יַגִּידוּ and let them proclaim his praise in the islands. There is a direct connection between proclaiming a serious theological truth (which has more serious implications than the truth of the courtroom) and in proclaiming (יַגִּידוּ, hifil jussive נָגַד) the praise of the Lord.

This verse is a minor chiasm, as the accents show:

merka + tipha + atnach + tipha + merka (+ silluq).

The Lord's "glory" and "praise" stand in the center of the verse, enclosed by the indirect object nouns "to the Lord" and "in the islands," flanked on the outside by the verbs of giving and proclaiming. Chiastic structures fill both Old and New Testaments, and it is rarely useful to talk about them in the pulpit unless help to explain a more difficult passage or unless one underscores an important truth. The same is probably true of centering, although centering is easier to explain quickly.

One more reference to the "islands" is a reminder from the prophet that Gentiles from all manner of unexpected places would become worshipers of the true God and enter into fellowship with all who are washed in the blood of the Lamb. Even such exotic and barbarous people as the blue-eyed denizens of the Black Forest and the blue-painted Celts in the misty islands northwest of Gaul would come to know Jesus.
