All the Israelites witnessed the descent of the fire and the glory of God on the House; they knelt with their faces to the ground and prostrated themselves, praising God, “For God is good, for God's steadfast love is eternal.”
וַיְהִ֣י אַבְרָ֔ם בֶּן־תִּשְׁעִ֥ים שָׁנָ֖ה וְתֵ֣שַׁע שָׁנִ֑ים וַיֵּרָ֨א יְהוָ֜ה אֶל־אַבְרָ֗ם וַיֹּ֤אמֶר אֵלָיו֙ אֲנִי־אֵ֣ל שַׁדַּ֔י הִתְהַלֵּ֥ךְ לְפָנַ֖י וֶהְיֵ֥ה תָמִֽים׃ וְאֶתְּנָ֥ה בְרִיתִ֖י בֵּינִ֣י וּבֵינֶ֑ךָ וְאַרְבֶּ֥ה אוֹתְךָ֖ בִּמְאֹ֥ד מְאֹֽד׃ וַיִּפֹּ֥ל אַבְרָ֖ם עַל־פָּנָ֑יו וַיְדַבֵּ֥ר אִתּ֛וֹ אֱלֹהִ֖ים לֵאמֹֽר׃
When Abram was ninety-nine years old, God appeared to Abram and said to him, “I am El Shaddai. Walk in My ways and be whole. I will establish My covenant between Me and you, and I will make you exceedingly numerous.” Abram threw himself on his face; and God spoke to him further,
“Avram prostrated himself” from joy over this welcome message.
“And God passed before him and proclaimed: God, God, compassionate and gracious God, slow to anger, abounding in loving-kindness and truth, extending loving-kindness to thousands of generations…and Moses made haste and bowed his head toward the earth and prostrated himself” (Exodus 34:6–8)
The Sages taught:
The term kidda indicates falling upon one’s face,
and so the verse states: “Then Bathsheba bowed [vatikkod] with her face to the ground” (I Kings 1:31).
Keria means descending upon one’s knees,
and so the verse states with regard to Solomon: “He rose from before the altar of the Lord, from kneeling [mikero’a] upon his knees” (I Kings 8:54).
Hishtaḥava’a, this is prostrating oneself while spreading one’s arms and legs in total submission,
and so the verse states that Jacob asked, in response to Joseph’s relating of his dream: “Shall I and your mother and your brothers indeed come to bow down [lehishtaḥavot] to you to the ground” (Genesis 37:10), i.e., spread out completely on the ground.

R. Itzchak said: Everything happened as a reward for prostrating. Abraham returned in peace from Mount Moriah only as a reward for prostrating. “And we will prostrate, and we will come back to you.” Israel were redeemed only as a reward for prostrating: “And the people believed … then they bowed their heads and prostrated” (Ex. 4:31). The Torah was given only as a reward for prostrating: “And prostrate y’all afar off” (Ex. 24:1). Hannah was remembered only as a reward for prostrating: “And they prostrated before the Lord” (I Sam. 1:19). The exiles will be reassembled only as a reward for prostrating: “And it shall come to pass in that day, that a great horn shall be blown; and they shall come that were lost … and that were dispersed … and they shall prostrate to God in the holy mountain at Jerusalem” (Isa. 27:13). The Temple was built only as a reward for prostrating: “Exalt y’all Ad-nai our God, and prostrate at God's holy mountain” (Ps. 99:9). The dead will come to life again only as a reward for prostrating: “O come, let us worship and bend the knee; let us kneel before Ad-nai our Maker (Ps 95:6).
