פירוש על במדבר 22:19

גם אתם [ABIDE] ALSO YE [HERE] — His mouth tripped him up (unwittingly he spoke the truth): you also in the end will go away disappointed as the former princes (Midrash Tanchuma, Balak 6).

ועתה שבו נא בזה גם אתם, "And now, you stay here also, etc." Bileam pleaded as he was afraid that these dignitaries would do what the Midianite delegates had done when they heard that Bileam was waiting to get G'd's instructions. The Midianite delegates at the time had gone home immediately without staying overnight as they anticipated Bileam's refusal (compare Bamidbar Rabbah 20,8). Now that the delegation was large and consisted of highly placed people, Bileam was afraid that they would not be willing to wait.

ועתה שבו נא בזה, “and now, please stay here, etc.” The word בזה refers to “this place.”
גם אתם הלילה, “also you, for the night.” [According to the cantillation there is a comma between “also you” and “night.” Ed.] Our sages claim that G’d punished Moav for this “night” which its emissaries spent with Bileam. They derive this from Isaiah 15,1 in which the prophet deals with G’d’s judgment of Moav. The prophet writes: “Ah, in the night Ar was sacked (a capital of Moav), Moav was ruined; Ah, in the night Kir was sacked, Moav was ruined.” The two nights which two delegations of Moav spent with Bileam attempting to get him to curse the Jewish people proved ultimately to boomerang on them. [This writer believes that the dropping of an atom bomb on Hiroshima and Nagasaki by the Americans also boomeranged, i.e. the men the U.S. lost in Korea and in Vietnam. Ed.].
