Leviticus 23:12

9 And the Lord said to Moses,

10 Say to the children of Israel, When you have come to the land which I will give you, and have got in the grain from its fields, take some of the first-fruits of the grain to the priest;

11 And let the grain be waved before the Lord, so that you may be pleasing to him; on the day after the Sabbath let it be waved by the priest.

12 And on the day of the waving of the grain, you are to give a male lamb of the first year, without any mark, for a burned offering to the Lord.

13 And let the meal offering with it be two tenth parts of an ephah of the best meal mixed with oil, an offering made by fire to the Lord for a sweet smell; and the drink offering with it is to be of wine, the fourth part of a hin.

14 And you may take no bread or dry grain or new grain for food till the very day on which you have given the offering for your God: this is a rule for ever through all your generations wherever you are living.

15 And let seven full weeks be numbered from the day after the Sabbath, the day when you give the grain for the wave offering;
