Numbers 22:31

22:31 Then the Lord opened Balaam’s eyes, and he saw the angel of the Lord standing in the way with his sword drawn in his hand; so he bowed his head and threw himself down with his face to the ground. 1 

1 tn The Hishtaphel verb חָוָה (khavah) – שָׁחָה (shakhah) with metathesis – has a basic idea of “bow oneself low to the ground,” and perhaps in some cases the idea of “coil up.” This is the normal posture of prayer and of deep humility in the ancient religious world.
