Para ahli sihir pun mencoba melakukan hal yang sama dengan ilmu rahasia mereka untuk mendatangkan kutu-kutu, tetapi mereka tidak mampu. Dan kutu-kutu itu ada pada manusia dan pada ternak.
Rashi
ותעל הצפרדע AND THE FROGS (lit. frog) CAME UP — Really there was only one frog, but when they struck at it, it was split into many swarms. This is a Midrashic explanation of the usage of the singular noun here (cf. Sanhedrin 67b; Exodus Rabbah 10:4). But as a literal explanation one must say that the swarm of the frogs is denoted by the singular form. Similar is, (v. 14) “and there was the כנם” — the swarm of insects, in old French pedulier; i. e. a swarm of lice. So, too, here, ותעל הצפרדע means: and there came up a grenouillière (old French) i. e. a swarm of frogs.
Rabbeinu Yonah
Ten miracles were performed for our ancestors in Egypt: As our forefathers were not hurt by all of the ten plagues that the Holy One, blessed be He, brought on the Egyptians in Egypt. And it is explicit in all of them except the plague of lice, about which it is written (Exodus 8:14), "and the lice were upon men" - and the Torah did not distinguish between Egypt and Israel. But it is a tradition in the hand of the sages that also with this [one] were they not struck .
Ibn Ezra
נזורו. They are gone away. Root נזר ‘to separate’ ; comp. וינזרו that they separate themselves (Lev. 22:2). נָזוֹרוּ is formed like יָבׂלוּ ‘ they could ’ (Exod. 8:14). Many take it as Niphal of זור ‘ to separate ’; comp. נָכוֹנוּ ‘ they are prepared ’ (Prov. 19:29); Niphal of כּוּן, ‘ to stand.
