'Feast of Weeks' in the Bible

And you shall observe the Feast of Weeks, of the first-fruits of wheat harvest, and the Feast of Ingathering at the year's end.

And in the day of the first-fruits, when you bring a new food offering to Jehovah in your Feast of Weeks, you shall have a holy convocation. You shall do no laboring work.

And you shall keep the Feast of Weeks to Jehovah your God with a measure of a free-will offering of your hand, which you shall give according as Jehovah your God has blessed you.

Three times in a year shall all your males appear before Jehovah your God in the place which He shall choose: in the Feast of Unleavened Bread, and in the Feast of Weeks, and in the Feast of Tabernacles. And they shall not appear before Jehovah empty,

even as the duty of every day required, offering according to the commandment of Moses, on the sabbaths and on the new moons, and on the solemn feasts, three times in the year, even in the Feast of Unleavened Bread, and in the Feast of Weeks, and in the Feast of Tabernacles.
