'Weeks' in the Bible

Seventy weeks have been fixed for your people and your holy town, to let wrongdoing be complete and sin come to its full limit, and for the clearing away of evil-doing and the coming in of eternal righteousness: so that the vision and the word of the prophet may be stamped as true, and to put the holy oil on a most holy place.

Have then the certain knowledge that from the going out of the word for the building again of Jerusalem till the coming of a prince, on whom the holy oil has been put, will be seven weeks: in sixty-two weeks its building will be complete, with square and earthwork.

And at the end of the times, even after the sixty-two weeks, one on whom the holy oil has been put will be cut off and have no ...; and the town and the holy place will be made waste together with a prince; and the end will come with an overflowing of waters, and even to the end there will be war; the making waste which has been fixed.

In those days I, Daniel, gave myself up to grief for three full weeks.

I had no pleasing food, no meat or wine came into my mouth, and I put no oil on my body till three full weeks were ended.
