54:5 כִּי בֹעֲלַיִךְ עֹשַׂיִךְ יְהוָה צְבָאוֹת שְׁמוֹ וְגֹֽאֲלֵךְ קְדוֹשׁ יִשְׂרָאֵל אֱלֹהֵי כָל־הָאָרֶץ יִקָּרֵֽא׃
Albert Barnes’ Notes on the Whole Bible For thy Maker is thine husband – Both these words, ‘maker’ and ‘husband,’ in the Hebrew are in the plural number. But the form is evidently the pluralis excellentiae – a form denoting majesty and honor (see 1 Samuel 19:13, 1 Samuel 19:16; Psalms 149:2; Proverbs 9:10; Proverbs 30:3; Ecclesiastes 12:1; Hosea 12:1). Here it refers to ‘Yahweh of hosts,’ necessarily in the singular, as Yahweh is one Deuteronomy 6:4. No argument can be drawn from this phrase to prove that there is a distinction of persons in the Godhead, as the form is so often used evidently with a singular signification.
