'Month' in the Bible

In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, all the fountains of the great deep came bursting through, and the windows of heaven were open;

And on the seventeenth day of the seventh month the ark came to rest on the mountains of Ararat.

And still the waters went on falling, till on the first day of the tenth month the tops of the mountains were seen.

And in the six hundred and first year, on the first day of the first month, the waters were dry on the earth: and Noah took the cover off the ark and saw that the face of the earth was dry.

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

And Laban said to him, Truly, you are my bone and my flesh. And he kept Jacob with him for the space of a month.
