וְאֵ֨ת שְׁתֵּ֤י קְצוֹת֙ שְׁתֵּ֣י הָעֲבֹתֹ֔ת תִּתֵּ֖ן עַל־שְׁתֵּ֣י הַֽמִּשְׁבְּצ֑וֹת וְנָתַתָּ֛ה עַל־כִּתְפ֥וֹת הָאֵפֹ֖ד אֶל־מ֥וּל פָּנָֽיו׃
А два других конца двух цепей прикрепи к двум сетам и прикрепи их к лопаткам ефода с лицевой стороны его;
Rashi on Exodus
ואת שתי קצות means, AND THE TWO EXTREMITIES OF שתי עבתת THE TWO PLAITED CHAINS — (Rashi points out that קצות is in the construct state) — i. e. the two ends of each cord
Siftei Chakhamim
Of the eiphod. . . As opposed to “toward the robe.” [Rashi knows this because if “Toward its face” meant toward the face of the kohein, what would it be as opposed to? The shoulder-straps of the eiphod are necessarily toward the face of the kohein who wears them.]
Chizkuni
ואת שתי קצות העבותות, “and the other two ends of the wreathen chains, etc.;” this somewhat cumbersome formulation is also found in Exodus 15,16, where we read: עד יעבור עמך ה', עד יעבור עם זו קנית, “until Your people of Hashem has passed, until this people You have acquired has passed;” a similar construction is also found in Psalms 93,3: נשאו נהרות ה' נשאו נהרות קולם, “the ocean raises its voice o Lord, the oceans sound their thunder.” These are just a few examples of this type of construction. The meaning of the verse is as follows: the two ends of the two wreathen chains shall be attached to the two golden frames, משבצות, mentioned in verse 13, between the ephod and spread across the breastplate.
