The Targum Pseudo-Jonathan stages Moses's greeting of Jethro with cinematic care: "Moses came forth from under the cloud of glory to meet his father-in-law, and did obeisance, and kissed him and made him a proselyte; and they asked of each other's welfare, and came to the tabernacle, the house of instruction" (Exodus 18:7).
Three things happen in a single line. First, Moses leaves the cloud of glory — the Shekhinah-canopy — to walk out and meet Jethro in the ordinary desert air. The Aramaic is making a point: the prophet does not stand on his rank. The one speaking with God steps down to hug his father-in-law.
Second, Moses "made him a proselyte." The conversion is performed immediately. The earlier verse had Jethro asking; this verse has the acceptance granted. There is no probation, no delay. When a sincere seeker arrives, the door opens.
Third — and most moving — they went together to "the tabernacle, the house of instruction." The Aramaic beit ulpana means a study hall. Jethro's first stop after conversion was not a feast but a classroom. He wanted to learn.
The takeaway: honor crosses generations through small gestures. Moses bows. Moses kisses. Moses teaches. And the Shekhinah does not begrudge him the moment — it waits patiently while family comes first.
