וְאִם־בְּאַחַ֖ת יִתְקָ֑עוּ וְנוֹעֲד֤וּ אֵלֶ֙יךָ֙ הַנְּשִׂיאִ֔ים רָאשֵׁ֖י אַלְפֵ֥י יִשְׂרָאֵֽל׃
And if they blow but with one, then the princes, the heads of the thousands of Israel, shall gather themselves unto thee.
Targum Jonathan on Numbers
If they blow upon one (only), the princes of the heads of the thousands of Israel shall assemble to thee.
