came to rest
"landed" or "stopped on solid ground"
in the seventh month, on the seventeenth day of the month ... tenth month
Because Moses wrote this book, it is possible he is referring to the seventh month and tenth month of the Hebrew calendar, but this is uncertain. (See: rc://en/ta/man/translate/translate-hebrewmonths and rc://en/ta/man/translate/translate-ordinal)
On the first day of the month
"On the first day of the tenth month"
This can be made more explicit: "appeared above the surface of the water." (See: rc://en/ta/man/translate/figs-explicit)
