Psalms 78:9

Ephraim — That Ephraim is here put for all Israel seems evident from the following verses, wherein the sins, upon which this overthrow is charged, are manifestly the sins of all the children of Israel, and they who are here called Ephraim are called Jacob and Israel, Psalms 78:21, and this passage may refer to that dreadful overthrow related, 1 Samuel 4:10, which is particularly named, because as the ark, so the flight was in that tribe. And the psalmist having related this amazing providence, falls into a large discourse of the causes of it, namely, the manifold sins of that and the former generations, which having prosecuted from hence to Psalms 78:60, he there returns to this history, and relates the sad consequence of that disaster, the captivity of the ark, and God's forsaking of Shiloh and Ephraim, and removing thence to the tribe of Judah and mount Zion. Bows — These are put for all arms.
