'Months' in the Bible

And she said to her father, "Let this thing be done for me: grant me two months so that I may go wander on the mountains and lament over my virginity, I and my companions.

And he said, "Go." He sent her away [for] two months, and she went with her friends, and she lamented over her virginity on the mountains.

At the end of the two months she returned to her father, and he did to her [according to] his vow; and {she did not sleep with a man}. And it became an annual custom in Israel

But his concubine felt repugnance toward him, and she left him and went to her father's house, to Bethlehem in Judah; she was there some four months.

But six hundred turned and fled toward the wilderness, to the rock of Rimmon, and they remained at the rock of Rimmon [for] four months.
