Isaiah 9:6
For to us a child is born, to us a son is given; and the government shall be upon his shoulder: and his name shall be called A wonder of a counselor is the mighty God, a father of eternity, a ruler of peace.
כִּי־יֶלֶד יֻלַּד־לָנוּ בֵּן נִתַּן־לָנוּ וַתְּהִי הַמִּשְׂרָה עַל־שִׁכְמוֹ וַיִּקְרָא שְׁמוֹ פֶּלֶא יוֹעֵץ אֵל גִּבּוֹר אֲבִי־עַד שַׂר־שָׁלוֹם
Compare with the ASV
For unto us a child is born, unto us a son is given; and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, Mighty God, Everlasting Father, Prince of Peace.
We rendered the name as the sentence it makes in Hebrew, keeping each word in its own form: "A wonder of a counselor is the mighty God, a father of eternity, a ruler of peace." The ASV divides it into five titles.
Why
One name
The Hebrew has no punctuation between the words.
More
After "his name shall be called" it gives a single name of six words.
Sentence names in Isaiah
Isaiah's own sons carry names that are short sentences: Shear-jashub, "a remnant shall return" (7:3), and Maher-shalal-hash-baz, "swift is the spoil, speedy is the prey" (8:3).
More
This version renders this name as a sentence in the same way.
The words, in their own forms
פֶּלֶא pele is a noun, "a wonder." יוֹעֵץ yoetz is a participle, "one who counsels, a counselor." אֵל גִּבּוֹר el gibbor is "mighty God." אֲבִי־עַד avi-ad is "a father of eternity." שַׂר־שָׁלוֹם sar-shalom is "a ruler (or prince) of peace." None of the words has the article, so none is supplied.
"Is" is supplied
Hebrew sentences of this kind have no word for "is"; English needs it.
The accents
The Masoretic accents mark pauses after pele, after gibbor and after ad.
"Wonderful, Counsellor, Mighty God, Everlasting Father, Prince of Peace" (ASV); "Pele-joez-el-gibbor-Abi-ad-sar-shalom," glossed "Wonderful in counsel is God the Mighty, the everlasting Father, the Ruler of peace" (JPS 1917); "The Mighty God is planning grace; the Eternal Father, a peaceable ruler" (JPS 1985).
