For there is no divination in Yaakov, and no sorcery in Israel; in due time it is said to Yaakov and to Israel what God has wrought.
Torah Temimah: Yerushalmi Shabbos 6:9 — R. Chanina son of R. Avahu: Bilam stood at the midpoint of the world’s days.
Sefaria — Yerushalmi Shabbos 6:9
English: R. Chanina son of R. Avahu said: That wicked one was standing at half the days of the world. What is the reason? “In due time it is said to Yaakov and to Israel what God has wrought.”
Chronological midrash from the word כעת.
Bilam’s moment is fixed at the midpoint of history — the verse’s “now” is cosmic, not merely situational.
