Amos 4:4 - Matthew Poole's English Annotations on the Holy Bible

Come to Beth-el, the known place of the moscholatria, calf-worship: see Amos 3:14. And transgress: this clears it to be an irony, either throwing them up to their obstinate way of sinning, giving them over as hopeless and incorrigible sinners, or deriding their trust and dependence on idols, to which they sacrificed at Beth-el: See what will be the issue hereof, how you shall succeed herein. At Gilgal multiply transgression; Gilgal was a place also where much idolatry was acted: see Hosea 4:15, Hosea 9:15 12:11. Since you will not be warned, go on, try whether God likes your sacrifices there as well as you like them, and whether they will be a means to preserve from judgments, or sins hastening judgments on you. Bring your sacrifices every morning: in the same irony God doth by Amos express his own displeasure, reprove their sin, and threaten it, though they imitate the instituted worship at Jerusalem, Exodus 29:38,39 Num 28:3,4. And your tithes after three years; God had, Deuteronomy 14:28, commanded every third year that all the tithe of that year should be brought, and laid up in a public storehouse; to this law, with the same irony, doth the prophet allude here.
