Three specific commands that Israel failed to follow
* They joined into relationships with Unbelievers! — They intermarried with and allied themselves with heathen outside of their faith (i.e., mixed marriage). Unbelievers will draw us away from God.
* They compromised worship — They failed to keep the Sabbath holy, i.e., they were no longer worshipping God as He set forth.
* They ceased to give to God! — They had forsaken the House of God!

We need renewed commitments to God and Worship
* because we are prone to spiritually wander and fall away from genuine worship, and
* because entropy cannot be reversed without work!

Nehemiah 9:33-38 Howbeit thou art just in all that is brought upon us; for thou hast done right, but we have done wickedly: 34 Neither have our kings, our princes, our priests, nor our fathers, kept thy law, nor hearkened unto thy commandments and thy testimonies, wherewith thou didst testify against them. 35 For they have not served thee in their kingdom, and in thy great goodness that thou gavest them, and in the large and fat land which thou gavest before them, neither turned they from their wicked works. 36 Behold, we are servants this day, and for the land that thou gavest unto our fathers to eat the fruit thereof and the good thereof, behold, we are servants in it: 37 And it yieldeth much increase unto the kings whom thou hast set over us because of our sins: also they have dominion over our bodies, and over our cattle, at their pleasure, and we are in great distress. 38 And because of all this we make a sure covenant, and write it; and our princes, Levites, and priests, seal unto it.
