"on day 20 of month 2." This is the second month of the Hebrew calendar. (See: [[rc://en/ta/man/translate/translate-hebrewmonths]] and [[rc://en/ta/man/translate/translate-ordinal]])
This can be stated in active form. Alternate translation: "the cloud rose up" or "Yahweh lifted the cloud" (See: [[rc://en/ta/man/translate/figs-activepassive]])
The tabernacle was also called by this longer name because the ark with the law of God was placed inside it. See how you translated this in [Numbers 1:50](../01/50.md).
