En-shemesh

fountain of the sun a spring which formed one of the landmarks
on the boundary between Judah and Benjamin (Josh. 15:7; 18:17).
It was between the "ascent of Adummim" and the spring of
En-rogel, and hence was on the east of Jerusalem and of the
Mount of Olives. It is the modern 'Ain-Haud i.e., the "well of
the apostles" about a mile east of Bethany, the only spring on
the road to Jericho. The sun shines on it the whole day long.
