וַיִּפֹּ֧ל אַבְרָהָ֛ם עַל־פָּנָ֖יו וַיִּצְחָ֑ק וַיֹּ֣אמֶר בְּלִבּ֗וֹ הַלְּבֶ֤ן מֵאָֽה־שָׁנָה֙ יִוָּלֵ֔ד וְאִ֨ם־שָׂרָ֔ה הֲבַת־תִּשְׁעִ֥ים שָׁנָ֖ה תֵּלֵֽד׃
Lalu Abraham sujud dengan wajahnya ke tanah dan tertawa gembira, dan ia berkata dalam hatinya: “Akankah seorang yang berumur seratus tahun mendapat anak? Dan Sara, yang berumur sembilan puluh tahun, akankah ia melahirkan?”
Akeidat Yitzchak
Although we have said that in order to prepare for supernatural knowledge, sound knowledge of natural law is a prerequisite, we find on occasion that this very familiarity with natural law acts as a hindrance to recognising when supernatural events are being invoked in history. Abraham and Sarah both laughed at the prediction of the angel that Sarah would give birth to a son at the age of ninety. They had to be reminded that "hayippaleh me-hashem davar" is anything too wonderful for G-d to accomplish? (Genesis 18,14) Similarly, even the prophet Jeremiah had to be reminded of this very fact when he doubted that the purchase of the field from his uncle was decreed by G-d, seeing that at first glance this ran counter to all that seemed logical. (Jeremiah 32,27). Also, when Moses observed the obstinacy of Pharaoh and the additional burdens imposed upon the Jewish people, (being at the beginning of his career) he turned to G-d asking "why did You cause things to become worse?" Moses had assumed that even when Hashgachah Peratit is at work there has to be logic, i.e. natural law has to be operative side by side. G-d corrected him saying "now you will see,” meaning once the supernatural is at work the very opposite of what natural law dictates may occur.
