John Wesley on Amos 4:4

Come to Beth - el - A strong irony, giving them over as incorrigible. At Gilgal - Gilgal was a place where much idolatry was acted. Every morning - In the same irony God reproves their sins tho' they imitated the instituted worship at Jerusalem. Three years - God had Deut 14:28, commanded every third year that all the tithe of that year should be brought, and laid up in a publick store - house.
