BIBLE DICTIONARY
Rain

In Palestine rain begins to fall late in October or early in November 9 ("the early rain"), and continues till about the end of December. The rainfall during January and February is usually small, but increases again during March and April ("the later rain"). Showers occur in May, and after this rain hardly ever falls until the end of September, though on the high ground the dews at night are often heavy. Some have reasoned that because no rain is mentioned in the Bible until Noah's day, it therefore did not rain until that time, but see Enoch's discussion of rain in Moses 7: 28.
