In the third month, when the children of Israel had gone forth from the land of Egypt, the same day they came into the wilderness of Sinai.
And ye shall keep it until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening.
And they took their journey from Elim, and all the congregation of the children of Israel came to the wilderness of Sin, which is between Elim and Sinai, on the fifteenth day of the second month after their departure from the land of Egypt.
This month shall be to you the beginning of months: it shall be the first month of the year to you.
Even to the morrow after the seventh sabbath shall ye number fifty days; and ye shall offer a new meat-offering to the LORD.
