Amos 2:4

God hath in the former verses threatened the enemies of his people for their outrages against his people; now he does threaten his people for their obstinacy in reiterated sins: see Amos 4:3. Despised; first slighted it, as if no excellency were in it, and next rejected it, as if it were not worthy of their observance; thus they refused with an abhorrence and detestation the law of the Lord, the whole law, partly by their immoralities and transgressions against the just commands of it, and partly by their false worship and idolatry: that law which was given with so much majesty and terror. on Mount Sinai; from which they should not have departed either to the right hand or to the left; that law which was perfect, holy, and useful, with which no fault could be justly found. So much the greater were their sins, because committed against so clear, full, and pure a law. Have not kept his commandments, i.e. they have greatly violated, as the Hebrew phrase importeth, Nehemiah 9:34 Daniel 9:5,10,11. Their lies; idols, which are a lie, whether commended to them by their false prophets, or chosen according to their own humour and fancy; all their false, superstitious, and idolatrous worship. Caused them to err; their idolatry was first their error, and this blinded them, made them more sottish and brutish, which was partly from the natural tendency of this sin, and partly from the just judgment of God, Romans 1:24 2 Thessalonians 2:10 -12. After the which, idols or lies, their fathers, first in Ur of the Chaldees, before Abraham was called, afterwards in Egypt, the wilderness, and in the land of Canaan itself, have walked, successively, one generation after another; idolatry, and superstition, and will-worship have been old hereditary sins, and now shall be punished.
