Moshe’s Tent
שמות יח,ה : וַּי בֹא יִתְרוֹ חֹתֵן מֹשֶה וּב נ יו וְאִשְתוֹ אֶל־מֹשֶה אֶל־הַּמִדְב ר אֲ שֶר־הוּא חֹנֶה ש ם הַּר ה אֱלֹקִ ים:
Baal haTurim notes that the word "choneh" also appears in Tehilim (34:8) "The angel of G-d encamps (choneh) around those who fear him." This teaches us that when Yisro arrived in the Camp of Yisrael, he did not need to enquire as to the location of Moshe's tent, since it was marked by the Cloud that surrounded it. (Angelic manifestations come in various forms, one of which is in a cloud formation)
