Did not the LORD quarantine Noah?

Genesis 7:11 In the six hundredth year of Noah’s life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.
 13 In the selfsame day entered Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah’s wife, and the three wives of his sons with them, into the ark;
 16b  and the LORD shut him in.

Did not the LORD quarantined Israel on Passover?

Exodus 12:21 Then Moses called for all the elders of Israel, and said unto them, Draw out and take you a lamb according to your families, and kill the passover.
 22 And ye shall take a bunch of hyssop, and dip it in the blood that is in the bason, and strike the lintel and the two side posts with the blood that is in the bason; and none of you shall go out at the door of his house until the morning.
 23 For the LORD will pass through to smite the Egyptians; and when he seeth the blood upon the lintel, and on the two side posts, the LORD will pass over the door, and will not suffer the destroyer to come in unto your houses to smite you.

Is there not a future quarantine?

Isaiah 26:20 Come, my people, enter thou into thy chambers, and shut thy doors about thee: hide thyself as it were for a little moment, until the indignation be overpast.

So, why do I so easily forget to meditate on the following, even when trouble is all around?

Proverbs 14:26 In the fear of the LORD is strong confidence: and his children shall have a place of refuge.

Psalms 27:5 For in the time of trouble he shall hide me in his pavilion: in the secret of his tabernacle shall he hide me; he shall set me up upon a rock.

Psalms 143:9 Deliver me, O LORD, from mine enemies: I flee unto thee to hide me.
