1Macc 9:42-49

42After they had fully avenged the blood of their brother, they returned to the marshes of the Jordan.43When Bacchides heard of this, he came with a large force on the sabbath day to the banks of the Jordan.44And Jonathan said to those with him, “Let us get up now and fight for our lives, for today things are not as they were before.45For look! the battle is in front of us and behind us; the water of the Jordan is on this side and on that, with marsh and thicket; there is no place to turn.46Cry out now to Heaven that you may be delivered from the hands of our enemies.”47So the battle began, and Jonathan stretched out his hand to strike Bacchides, but he eluded him and went to the rear.48Then Jonathan and the men with him leaped into the Jordan and swam across to the other side, and the enemy did not cross the Jordan to attack them.49And about one thousand of Bacchides' men fell that day.
