GEN1122 In a beautiful legend [Midrash Psalms 37] related to Abraham, we are again reminded of the virtues of hospitality.   In [this verse], Abraham plants an eishel (tamarisk tree) in Beer Sheba, and there he calls on the name of Eternal everlasting God.   The rabbis interpreted the Hebrew word eishel as an acronym, represented eating, drinking, and escorting, thus suggesting that the virtue of hospitality is analogous to a fruit-bearing tree, for by means of hospitality, Abraham planted a tree for himself in heaven that would produce for him fruits of reward.
