“When Bacchides learned of this, he tried to kill him. But Jonathan and his brother Simon, and all who were with him, heard of it. They fled into the wilderness of Tekoa and camped by the water of the pool of Asphar. Bacchides found this out on the Sabbath day. He with all his army crossed the Jordan.”
The Syrian General Bacchides heard about Jonathan and tried to kill him. Jonathan was joined by his brother Simon as they fled to the wilderness of Tekoa, which was about 16 miles southeast of Jerusalem. The pool of Asphar was about 3 miles further south of Tekoa. General Bacchides found them on the Sabbath as he crossed the Jordan River with his army.
