Question: Are the rules in Exodus 12: 10, 16, and 19 unique to the Feast of Unleavened Bread?
Answer: The Feast of Passover is kept during the night of the 14th of the first Luni-solar month. The 7 day Feast of Unleavened Bread begins on the morning of the 15th and ends on the 21st at dusk. The 15th is a High Sabbath because it always coincides with the weekly Sabbath.
There are rules which are unique to the convocations / Sabbaths of the Feast of Unleavened Bread. These rules obviously supersede those of the weekly Sabbath and they do not apply to any other Feast.
1. Exodus 12:10 allows for [making a fire] to burn any remains of the Passover lamb on the High Sabbath of the 15th.
2. Verse 16 allows meal preparation on this High Sabbath which always coincides with the weekly Sabbath on the 15th.
3. Verse 19 has an implied allowance to remove leaven from their houses.
4. Meal preparation is also allowed on all the days of the feast including the Sabbath / convocation on the 21st.
It should also be noted that in the case of the ‘back to back’ Sabbaths in the Feast of Unleavened Bread, preparation including the cooking of meals can be done during the NIGHT hours separating the two Sabbath DAYS.
These special allowances demonstrate the great love and compassion of Yahuwah for His children under the strenuous circumstances and inconveniences surrounding their hurried departure from Egypt. Hence the unleavened bread etc., they could not wait for the dough to 'rise' as usual...
Read the whole chapter (Exodus 12):
11 And thus shall ye eat it; with your loins girded, your shoes on your feet, and your staff in your hand; and ye shall eat it in haste: it is Yahuwah’s passover.
34 And the people took their dough before it was leavened, their kneading troughs being bound up in their clothes upon their shoulders.
39 And they baked unleavened cakes of the dough which they brought forth out of Egypt, for it was not leavened; because they were thrust out of Egypt, and could not tarry, neither had they prepared for themselves any victual.
