1 Samuel 3: 9

1 Samuel 3:9 (New International Version)

So Eli told Samuel, "Go and lie down,

and if he calls you,

say, 'Speak, LORD,

for your servant is listening.' "

So Samuel went and lay down in his place.

d. Speak, LORD, for Your servant hears: Samuel is given wise counsel by Eli. Eli tells Samuel to make himself available for God to speak (Go, lie down); he tells Samuel to not be presumptuous about God speaking (if He calls you); he tells Samuel to respond to the word of God (Speak, LORD); and he tells Samuel to humble himself before God and His word (Your servant hears).
