Numbers 32:38

ואת נבו ואת בעל מעון מוסבת שם AND NEBO AND AND BAAL-MEON, THEIR NAMES BEING CHANGED — Nebo and Baal-Meon were names of idols, and the Ammonites used to call their cities by the names of their gods. The children of Reuben therefore changed their names into other names. This is the meaning of מוסבת שם: Nebo and Baal-Meon were changed to other names. ואת שבמה AND SIBMAH — i.e., they built (cf. v. 37) Sibmah also. This is identical with Sebam that is mentioned above (v. 3).

וְאֶת־נְב֞וֹ וְאֶת־בַּ֧עַל מְע֛וֹן מֽוּסַבֹּ֥ת שֵׁ֖ם וְאֶת־שִׂבְמָ֑ה וַיִּקְרְא֣וּ בְשֵׁמֹ֔ת אֶת־שְׁמ֥וֹת הֶעָרִ֖ים אֲשֶׁ֥ר בָּנֽוּ׃

and Nevo, and Ba῾al-me῾on, (their names being changed,) and Sivma: and gave other names to the cities which they built.
