Amos 4:1 says, Hear this word, ye kine of Bashan, that are in the mountain of Samaria, which oppress the poor, which crush the needy, which say to their masters, Bring, and let us drink.  Amos brings some of God's specific charges against Israel here.  They were in their nice houses, as stated in the last chapter, while taking advantage of the poor.  I do not believe that God ever expects His people to grow more and more rich in the things of this world and feel that these riches are all for their own benefit.  God's word, the Bible, has a lot to say about taking care of the poor and needy around us.  We cannot, as God's people, look down on the poor as if they deserve to be poor because of their own actions.  Even if we can somehow look down on what we see as their sin, we must still love the sinner.  Verse two declares, The Lord GOD hath sworn by his holiness, that, lo, the days shall come upon you, that he will take you away with hooks, and your posterity with fishhooks.  God's people, who were His in name only, were to be taken away captive, and their prosperity taken away with them.  Professing to be a child of God without any real relationship with Him through Christ will only bring an ultimate destruction of all that a person is so proud of.  God's gives us freedom over sin through our faith in Christ, but if we do not have a personal relationship with Christ, all the riches in the world mean nothing.  Verse three states,  And ye shall go out at the breaches, every cow at that which is before her; and ye shall cast them into the palace, saith the LORD.  God had provided Israel with a good land, but like cattle in a good pasture, they were not satisfied.  Now, since they had looked to the world for satisfaction, they were going to be removed from that land.  When we are not satisfied with God's blessings and begin to look to the world for satisfaction, then we are in danger of losing God's material blessings.  Verse four states, Come to Bethel, and transgress; at Gilgal multiply transgression; and bring your sacrifices every morning, and your tithes after three years: I believe that this is just a warning against empty, ritualistic worship without a relationship with God.  We may be in church faithfully and give above a tithe, but if there is no relationship with Christ as Savior and Lord, then we are wasting our time and money.  Verse five says, And offer a sacrifice of thanksgiving with leaven, and proclaim and publish the free offerings: for this liketh you, O ye children of Israel, saith the Lord GOD.  This is a continuation of the warning against empty worship.  It is done for our benefit, and not for God's glory.
