22 And it came to pass, that on the sixth day they gathered twice as much bread, two omers for one man: and all the rulers of the congregation came and told Moses.

23 And he said unto them, This is that which the Lord hath said, To morrow is the rest of the holy sabbath unto the Lord: bake that which ye will bake to day, and seethe that ye will seethe; and that which remaineth over lay up for you to be kept until the morning.

24 And they laid it up till the morning, as Moses bade: and it did not stink, neither was there any worm therein.

25 And Moses said, Eat that to day; for to day is a sabbath unto the Lord: to day ye shall not find it in the field.

26 Six days ye shall gather it; but on the seventh day, which is the sabbath, in it there shall be none.

God had given two points of instruction thus far:

1. Every household was to gather one omer per person, which would be just the right amount for the day.

2. No one was to keep leftovers for the next day.

Certain Israelites had already tried defying the second rule, gathering extra rather than trusting the Lord to provide again in the morning, and all the extra had spoiled. It just wasn’t going to work for the people not to follow God’s directions in this matter, they needed to not make exceptions to His rules.

But then, as an interesting twist, God, Himself, presented a third rule that carved out an exception to his first two:

3. On the day before the sabbath they were permitted to gather two omers per person, one for the day before the sabbath and one for the sabbath.

The purpose of this rule being, of course, to keep the Israelites from having to labor on the sabbath. Thus, God was providing a valid way to do the exact thing that had been invalid when done by the disobedient Israelites just prior.

The lesson here is clear. When God gives us His commandments, He can also provide special limitations or exceptions to them, but we cannot. Some things are wrong inherently, and some things are wrong because they have been forbidden for that time. In either case, one is only right when applying the commandment of God that is relevant to that situation, and wrong when doing anything other than God’s commandment for that situation.

Some people may balk at the idea of God creating set times when a behavior is right and set times when it is wrong, but any collection of laws has this sort of nuance. For example, one may drive down the road at the posted speed limit, except at a red light they must stop until it turns green, except when that red light is flashing and they should treat it like a stop sign, except when there is a police officer directing traffic at that intersection. Are the rules ambiguous or arbitrary because they change what behavior is correct based on the circumstance? No. In each instance there is one right behavior, and there is a good reason for it. So it is with God’s laws.
