'Weeks' in the Bible

"You must observe the Feast of Weeks -- the firstfruits of the harvest of wheat -- and the Feast of Ingathering at the end of the year.

"'You must count for yourselves seven weeks from the day after the Sabbath, from the day you bring the wave offering sheaf; they must be complete weeks.

"'You must count off seven weeks of years, seven times seven years, and the days of the seven weeks of years will amount to forty-nine years.

"'Also, on the day of the first fruits, when you bring a new grain offering to the Lord during your Feast of Weeks, you are to have a holy assembly. You must do no ordinary work.

You must count seven weeks; you must begin to count them from the time you begin to harvest the standing grain.

Then you are to celebrate the Festival of Weeks before the Lord your God with the voluntary offering that you will bring, in proportion to how he has blessed you.

Three times a year all your males must appear before the Lord your God in the place he chooses for the Festival of Unleavened Bread, the Festival of Weeks, and the Festival of Temporary Shelters; and they must not appear before him empty-handed.

At that time Solomon and all Israel with him celebrated a festival before the Lord our God for two entire weeks. This great assembly included people from all over the land, from Lebo Hamath in the north to the Brook of Egypt in the south.

They do not say to themselves, "Let us revere the Lord our God. It is he who gives us the autumn rains and the spring rains at the proper time. It is he who assures us of the regular weeks of harvest."

"Seventy weeks have been determined concerning your people and your holy city to put an end to rebellion, to bring sin to completion, to atone for iniquity, to bring in perpetual righteousness, to seal up the prophetic vision, and to anoint a most holy place.

So know and understand: From the issuing of the command to restore and rebuild Jerusalem until an anointed one, a prince arrives, there will be a period of seven weeks and sixty-two weeks. It will again be built, with plaza and moat, but in distressful times.

Now after the sixty-two weeks, an anointed one will be cut off and have nothing. As for the city and the sanctuary, the people of the coming prince will destroy them. But his end will come speedily like a flood. Until the end of the war that has been decreed there will be destruction.

In those days I, Daniel, was mourning for three whole weeks.

I ate no choice food; no meat or wine came to my lips, nor did I anoint myself with oil until the end of those three weeks.
