'Tree' in the Bible

And Saul tarried in the uttermost part of Gibeah under a pomegranate tree which is in Migron: and the people that were with him were about six hundred men;

When Saul heard that David was discovered, and the men that were with him, (now Saul abode in Gibeah under a tree in Ramah, having his spear in his hand, and all his servants were standing about him;)

And they took their bones, and buried them under a tree at Jabesh, and fasted seven days.
