Leviticus 23:22
And when ye reap the harvest of your land, thou shalt not make clean riddance of the corners of thy field when thou reapest, neither shalt thou gather any gleaning of thy harvest: thou shalt leave them unto the poor, and to the stranger: I am the LORD your God.
I commanded
Nehemiah 7:3
And I said unto them, Let not the gates of Jerusalem be opened until the sun be hot; and while they stand by, let them shut the doors, and bar them: and appoint watches of the inhabitants of Jerusalem, every one in his watch, and every one to be over against his house.
Exodus 31:14-17
14
Ye shall keep the sabbath therefore; for it is holy unto you: every one that defileth it shall surely be put to death: for whosoever doeth any work therein, that soul shall be cut off from among his people.
15
Six days may work be done; but in the seventh is the sabbath of rest, holy to the LORD: whosoever doeth any work in the sabbath day, he shall surely be put to death.
16
Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant.
17
It is a sign between me and the children of Israel for ever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed.
Jeremiah 17:19-22
19
Thus said the LORD unto me; Go and stand in the gate of the children of the people, whereby the kings of Judah come in, and by the which they go out, and in all the gates of Jerusalem;
20
And say unto them, Hear ye the word of the LORD, ye kings of Judah, and all Judah, and all the inhabitants of Jerusalem, that enter in by these gates:
21
Thus saith the LORD; Take heed to yourselves, and bear no burden on the sabbath day, nor bring it in by the gates of Jerusalem;
22
Neither carry forth a burden out of your houses on the sabbath day, neither do ye any work, but hallow ye the sabbath day, as I commanded your fathers.
