Numbers 10:36

‘שובה ה [AND WHEN IT RESTED HE SAID] שובה O LORD — Menachem ben Seruk renders it (the word שובה) by an expression denoting “rest”. Similar is (Isaiah 30:15) “In rest (בשובה) and tranquility shall ye be saved” (cf. Ibn. Ezra). רבבות אלפי ישראל [GIVE REST O LORD UNTO] THE MYRIADS OF THOUSANDS OF ISRAEL — This teaches us that the Shechinah does not rest upon Israel if they are less in number than twenty-two thousand (Yevamot 64a; Sifrei Bamidbar 84:5).

וּבְנֻחֹ֖ה יֹאמַ֑ר שׁוּבָ֣ה יְהֹוָ֔ה רִֽבְב֖וֹת אַלְפֵ֥י יִשְׂרָאֵֽל׃ ׆ {פ}

And when it rested, he said, Return, Lord, to the ten thousand thousands of Yisra᾽el.
