Commentary for Judges 4:5

Under [Devorah's] date tree. She owned date trees in Yericho.

Under the date palm: So that she not be secluded with the men who would come to her for judgement, she fixed her place under the date palm. As there is no place for seclusion there (Megillah 14:1).

Tomer: It is like, tamar (date). And Yonatan translated the verse (in the Targum) like this, "And she sat in the town, etc." And it can be said, according to its plain sense, that she had a house under a date palm. And that which it said, Devorah, (again) is additional identification, for she was already mentioned. And it stated, "And she," [because] we knew that it was speaking about her, and [since] it mentioned, Devorah, after this for additional identification. As this is the way of the language, as in (Genesis 6:9), "These are the generations of Noach, Noach," and others beside it.
