High Holy Days
Understanding the High Holy Days of the Lord is a vital part of your biblical walk. The Laws of God governs and instructs us on how to worship him.  He rested on the 7th day and left us the example and instructions to do so as well.  We, the Israelites who were given the laws of God must return to them without bittern constraint but willingly.

No Purchasing and Selling
Nehemiah 10:31
31 And if the people of the land bring ware or any victuals on the sabbath day to sell, that we would not buy it of them on the sabbath, or on the holy day: and that we would leave the seventh year, and the exaction of every debt.
Nehemiah 13:15
15 In those days saw I in Judah some treading wine presses on the sabbath, and bringing in sheaves, and lading asses; as also wine, grapes, and figs, and all manner of burdens, which they brought into Jerusalem on the sabbath day: and I testified against them in the day wherein they sold victuals.
16 There dwelt men of Tyre also therein, which brought fish, and all manner of ware, and sold on the sabbath unto the children of Judah, and in Jerusalem. 17 Then I contended with the nobles of Judah, and said unto them, What evil thing is this that ye do, and profane the sabbath day?
18 Did not your fathers thus, and did not our God bring all this evil upon us, and upon this city? yet ye bring more wrath upon Israel by profaning the sabbath.
19 And it came to pass, that when the gates of Jerusalem began to be dark before the sabbath, I commanded that the gates should be shut, and charged that they should not be opened till after the sabbath: and some of my servants set I at the gates, that there should no burden be brought in on the sabbath day.
20 So the merchants and sellers of all kind of ware lodged without Jerusalem once or twice.
21 Then I testified against them, and said unto them, Why lodge ye about the wall? if ye do so again, I will lay hands on you. From that time forth came they no more on the sabbath.
