Act 10:9. On the morrow, as they went on their journey, and drew nigh unto the city, Peter went up upon the housetop to pray about the sixth hour: 10. And he became very hungry, and would have eaten: but while they made ready, he fell into a trance,
And saw heaven opened, and a certain vessel descending unto him, as it had been a great sheet knit at the four corners, and let down to the earth:
1. certain vessel descending unto him
Hosea 8:8. Israel is swallowed up: now shall they be among the Gentiles as a vessel wherein is no pleasure.
2. a great sheet knit at the four corners
So all the men of Israel were gathered against the city, knit together as one man.
Act 10:12 Wherein were all manner of fourfooted beasts of the earth, and wild beasts, and creeping things, and fowls of the air.
What are the Beast.? Ecclesiastes 3:18. I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts.
13. And there came a voice to him, Rise, Peter; kill, and eat. 14. But Peter said, Not so, Lord; for I have never eaten any thing that is common or unclean.
Act 10:15. And the voice spake unto him again the second time, What God hath cleansed, that call not thou common.
Linking yet another Prophecy Ezekiel 37:21. And say unto them, Thus saith the Lord GOD; Behold, I will take the children of Israel from among the heathen, whither they be gone, and will gather them on every side, and bring them into their own land: 22. And I will make them one nation in the land upon the mountains of Israel; and one king shall be king to them all: and they shall be no more two nations, neither shall they be divided into two kingdoms any more at all:
23. Neither shall they defile themselves any more with their idols, nor with their detestable things, nor with any of their transgressions: but I will save them out of all their dwellingplaces, wherein they have sinned, and will cleanse them: so shall they be my people, and I will be their God.
So all Israel will be scattered among the Gentiles by Ships as the prophecy stated in Deuteronomy 28:68. and would need to be cleansed by repenting in Christ for their sins.
