'Of The Month' in the Bible

In the first month, on the fourteenth day of the month at evening, you shall eat unleavened bread, until the one and twentieth day of the month at evening.

You shall keep the feast of unleavened bread: (you shall eat unleavened bread seven days, as I commanded you, in the time appointed of the month Abib; for in it you came out from Egypt: and none shall appear before me empty:)

The feast of unleavened bread shall you keep. Seven days you shall eat unleavened bread, as I commanded you, in the time of the month Abib: for in the month Abib you came out from Egypt.

And it came to pass in the first month in the second year, on the first day of the month, that the tabernacle was raised up.
