The Lord said to Samuel, “How long do you intend to mourn for Saul? I have rejected him as king over Israel. ¹  Fill your horn with olive oil and go! I am sending you to Jesse in Bethlehem, ²  for I have selected a king for myself from among his sons.” ³ 

Saul quickly fell full length on the ground and was very afraid because of Samuel’s words. He was completely drained of energy, ¹  not having eaten anything ²  all that day and night.
