Exodus 12:13

13 Forsooth [the] blood shall be to you into (a) sign, in the houses in which ye shall be; and I shall see the blood, and I shall pass (over) you; neither a wound destroying shall be in you, when I shall smite the land of Egypt. (And the blood on the houses in which ye shall be, shall be a sign of you; and I shall see the blood, and I shall pass over you; and there shall be no destroying wound inflicted upon you, when I shall strike the land of Egypt.)

Exodus 12:13 Meaning and Commentary

Exodus 12:13

And the blood shall be to you for a token upon the houses
where you are
The blood of the passover lamb being sprinkled on the two sideposts and upper doorposts of the houses inhabited by the Israelites, or where they were eating the passover; this should be a sign or token to them of the Lord's making good his promises, to them, and so of their safety, and to the destroying angel not to enter therein, but pass by and save them:

and when I see the blood, I will pass over you;
for which reason this ordinance now instituted was called the passover, because the Lord, on sight of the blood sprinkled, passed over the houses of the Israelites to those of the Egyptians; or "leaped", as Jarchi says, the word signifies, skipped from one Egyptian house to another, passing by that of the Israelites:

and the plague shall not be upon you, to destroy you, when I smite the
land of Egypt,
the pestilence with which the firstborn should be destroyed.

(And I shall pass through the land of Egypt on that night, and I shall strike down all the first-born in the land of Egypt, from man unto beast; and I the Lord shall execute judgement against all the gods of Egypt.)

(And the blood on the houses in which ye shall be, shall be a sign of you; and I shall see the blood, and I shall pass over you; and there shall be no destroying wound inflicted upon you, when I shall strike the land of Egypt.)
