וְיֵז And sprinkled. It is similar in form to וַיֵט and he stretched forth (Ex. 9:23).

3. זַ֣עַם “Indignation” - At first there was rain, as is stated, “as HaShem rained down.” (Ex. 9:23) From the power of the wind it became hail, as Scripture states, “Storm wind that executes His command,” (Ps. 148:8)

A kabbalistic approach: The word כל, “all,” in the expression את כל מגפותי, “all My plagues,” may be understood as similar to the word “all” in ולא יעיר כל חמתו, “and did not give vent to all His fury” (Psalms 78,38). The meaning of the word in that context is the attribute called כל. This attribute describes G’d’s anger. Here too the Torah describes that this plague will be the result of G’d’s anger at Pharaoh having failed to respond to earlier methods to discipline him. Henceforth this attribute would be employed in order to humble him. This is why Moses needed to raise his hands (verse 29) when he prayed for the removal of this plague when the time came. He had not had to do this when he prayed for the removal of any of the preceding plagues. People had actually been dying from fear when they merely heard the sound of the hail. Seeing this plague was the result of the combined efforts of G’d and His celestial court it was more severe than the plagues preceding it. This fact is alluded to in the Torah especially mentioning the word קולות as part of the actual plague in verse 23: “and G’d sent thunder and hail.” Seeing this had been so, Moses had to make an increased effort in his prayer to stop the plague by using also his outstretched hands in prayer. He needed to sanctify all his ten fingers. The symbolism contained in raising one’s hands heavenwards in prayer is that it is an expression of one’s awareness of the source of the disaster which one wants to prevent by one’s prayer and by invoking G’d’s attribute of Mercy towards what transpires on earth. The plague’s effect on Pharaoh was that for the first time he publicly acknowledged that he and his people had sinned, that G’d was righteous (verse 27). As soon as Moses engaged in this kind of prayer the hail, etc. ceased (not on the next day as in previous plagues).
