Abraham planted a tamarisk tree in Beer-sheba, and there he called on the name of Yahweh, the Everlasting God. Bible see other translations

“planted a tamarisk tree.” The tamarisk could grow in very arid regions, such as the Negev, and provide shade. There is no indication that Abraham planted the tree as some kind of religious act or dedication to God. It is more likely that he intended to stay there in Beer-sheba, or have a place where, as he tented from place to place, he could return and have shade. Preparing for the future and providing for others are hallmarks of a wise and godly person.
