וְשַׂמְתָּ֞ אֶת־שְׁתֵּ֣י הָאֲבָנִ֗ים עַ֚ל כִּתְפֹ֣ת הָֽאֵפֹ֔ד אַבְנֵ֥י זִכָּרֹ֖ן לִבְנֵ֣י יִשְׂרָאֵ֑ל וְנָשָׂא֩ אַהֲרֹ֨ן אֶת־שְׁמוֹתָ֜ם לִפְנֵ֧י יְהוָ֛ה עַל־שְׁתֵּ֥י כְתֵפָ֖יו לְזִכָּרֹֽן׃ (ס)
And thou shalt put the two stones upon the shoulder-pieces of the ephod, to be stones of memorial for the children of Israel; and Aaron shall bear their names before the LORD upon his two shoulders for a memorial.
Targum Jonathan on Exodus
thou shalt engrave the two gems according to the names of the sons of Israel in their work round about; inset in gold shalt thou make them. And thou shalt fix the two gems upon the shoulders of the ephod, to be set for a memorial of righteousness for the sons, of Israel; and Aharon shall bear the names of the sons of Israel upon his two shoulders for a memorial.
