Question

I saw in the translation of Jonathan ben Uzziel on the verse, “I bore you on eagles’ wings,” that he explains that the children of Israel, at the time of offering and eating the Paschal sacrifice in Egypt, did this in the Land of Israel, in Jerusalem, by being carried there on clouds.
Is there any explanation for this? It raises many questions for any reader.
What was the purpose of it? What would it help if there was not yet a Temple, and the place had not yet been sanctified? Why did they not also leave Egypt in this easy way? And there are many other questions that seem to contradict all the commands not to leave the houses, and “I will see the blood,” and so on.
With thanks and best regards, we would be glad for an explanation of such a matter, and in general what the source is for explaining something like this—whether by divine inspiration or based on some knowledge and ancient source.
Shabbat Shalom
