Hisgalus 9:3-5

Orthodox Jewish Bible

³ And out of the smoke came forth arbeh (locusts) to ha’aretz (the earth), and samchut (authority) was given to them like the samchut of the akrabei ha’aretz (scorpions of the earth). [SHEMOT 10:12-15]

⁴ And it was told them that they should not harm the grass of ha’aretz (the earth) nor any greenery nor any etz (tree), except the Bnei Adam, all who do not have the chotam (seal) of Hashem on their metsakhim (foreheads) (YECHEZKEL 9:4).

⁵ And it was given to them that they should not kill them, but that they will be tormented chamishah chodashim (five months). Their torment is as the torment of an akrav when it stings a man.
