'Months' in the Bible

At which season Moses was born, and was exceeding fair; and he was nourished three months in his father's house.

And he dwelt there a year and six months, teaching the word of God among them.

And he entered into the synagogue, and spake boldly for the space of three months, reasoning and persuading as to the things concerning the kingdom of God.

And when he had spent three months there, and a plot was laid against him by Jews as he was about to set sail for Syria, he determined to return through Macedonia.

And after three months we set sail in a ship of Alexandria which had wintered in the island, whose sign was The Twin Brothers.
