Leviticus 23:15

And ye shall count unto you from the morrow after the sabbath, from the day that ye brought the sheaf of the wave offering; seven sabbaths shall be complete:

"'You shall count from the next day after the Sabbath, from the day that you brought the sheaf of the wave offering; seven Sabbaths shall be completed:

And ye shall count unto you from the morrow after the sabbath, from the day that ye brought the sheaf of the wave-offering; seven sabbaths shall there be complete:

`And ye have numbered to you from the morrow of the sabbath, from the day of your bringing in the sheaf of the wave-offering: they are seven perfect sabbaths;

From the day after the Sabbath, the day you brought the sheaf of the wave offering, you are to count off seven full weeks.
