Мелахим А 8:54 Галаха: Mishneh Torah, Prayer and the Priestly Blessing

Genuflection. The worshiper bends the knees five times in every [Amidah] prayer,^*Prayer, recited standing. at the beginning and at the end of the first blessing; at the beginning and the end of the thanksgiving blessing (which begins "We thank Thee"); and after the conclusion of the prayer. The knees are then bent, the worshiper steps backwards three paces, and with knees bent, bows to the left, then to the right, and then raises his head. When he bends the knees the first four times, he does so while uttering the word "Blessed" and resumes the erect posture at the word "O Lord." This rule applies to the layman. The high priest however bends the knees at the beginning and end of every blessing. The king bows his head at the beginning of the [Amidah] prayer and does not raise it till he has concluded it.

Prostration. After he has raised his head, subsequent to the fifth genuflection, the worshiper seats himself on the floor and "falls upon his face" and offers all the supplications he pleases. Genuflection, wherever mentioned, always refers to bending the knees. Kidah means "falling on the face" [with knees bent]. Hishtahvayah means stretching out the hands and feet, so that one is lying prone with face to the ground.

The lesson from the Prophets on the first day is that beginning, "Behold, a day of the Lord cometh" (Zechariah 14:1-21). The lesson from the Prophets on the second day is that beginning, "And all the men of Israel assembled themselves unto King Solomon" (I Kings 8:2-21). On the eighth day, the section from the Pentateuch is that beginning, "Every first born" (Deuteronomy 15:19-16:17). The lesson from the Prophets is that beginning, "And it was so that when Solomon had made an end of prayer" (I Kings 8:54-66). On the following day, the weekly portion beginning, "And this is the blessing" (Deuteronomy 33:1-34:12) is read. The lesson from the Prophets is that beginning, "And Solomon stood" (I Kings 8:22-53). Some read, as the lesson from the Prophets that beginning, "Now it came to pass after the death of Moses" (Joshua 1:1-18).
