'Month' in the Bible

In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, on that same day all the fountains of the great deep were broken up, and the windows of heaven were opened.

And the ark rested in the seventh month, on the seventeenth day of the month, on the mountains of Ararat.

And the waters abated continually until the tenth month: in the tenth month, on the first of the month, the tops of the mountains were seen.

And it came to pass in the six hundred and first year, in the first month, on the first of the month, that the waters were dried up from the earth. And Noah removed the covering of the ark, and looked, and behold, the surface of the ground was dried.

And in the second month, on the twenty-seventh day of the month, the earth was dry.
