How many kids did Samson in the Bible have?
none
That is not true. One of the Midrashim - which is the Hebrew
commentary on the Hebrew bible - says that Samson (and Delilah) did
indeed have children and that they lived elsewhere in the land of
Israel, in a place where gold was: Havilah. So, the Bible doesn't
really mention children perhaps, but commentators to the Bible, who
studied the Bible in the years after the second destruction of the
Hebrew Temple, interpreted the story with children to Samson and
Delilah. I guess those children were half Jewish (or Hebrew) and
half non-Jewish(Philistines).
