Why does the Torah mention the hail and the fire separately, and in the following Pasuk, add that the fire was contained inside the hail?
1.
Oznayim la'Torah: Because Hashem first sent a regular hail-storm accompanied by thunder, 1 and the fire that was caused by the thunder reached the ground independently; and it was only when Par'oh did not doTeshuvah that the fore and water made peace to form a plague.
1
Oznayim la'Torah: To encourage Par'oh to do Teshuvah.
