They gathered together to Mizpah, and drew water, and poured it out before Yahweh, and fasted on that day, and said there, We have sinned against Yahweh. Samuel judged the children of Israel in Mizpah.
After the tabernacle left Shiloh, the Israelites may have pitched it at Mizpah. Since Samuel offered a burnt offering there (1 Samuel 7:9), perhaps that is where the tabernacle stood. Nevertheless at this time the Israelites made offerings to God at other places too (cf. 1 Samuel 7:17).
