תּלמוד אויף מלכים א 8:34

Our rabbis have taught: Kidah means falling upon the face, as it says, “Then Bathsheba bowed [vatikod] with her face to the earth” (I Kings 1:31). Keri’ah means going down on the knees, and so it says, “[Solomon arose] from kneeling [mikroa] on his knees” (I Kings 8:34). Hishtahava’ah means spreading out of the hands and feet, as it says, “Shall I and your mother and your brothers come to prostrate ourselves [lehishtahavot] before you to the ground” (Genesis 37:10).
