Asalamu Alykum Deliverance
28:29Then, when Moses had fulfilled the term, and was travelling with his housefolk, he saw in the distance a fire and said unto his housefolk: Bide ye (here). Lo! I see in the distance a fire; peradventure I shall bring you tidings thence, or a brand from the fire that ye may warm yourselves.
28:30 And when he reached it, he was called from the right side of the valley in the blessed field, from the tree: O Moses! Lo! I, even I, am Allah, the Lord of the Worlds;
When Moses reached the fire he was then called to the right side of the valley where the tree was.
The translation of the word chajrata is a tree.
Hope that helps Insha'Allah
