"Then he prayed, 'Lord, God of my master Abraham, make me successful today, and show kindness to my master Abraham. See, I am standing beside this spring, and the daughters of the townspeople are coming out to draw water. May it be that when I say to a young woman, "Please let down your jar that I may have a drink," and she says , "Drink, and I'll water your camels too" - let her be the one you have chosen for your servant Isaac. By this I will know that you have shown kindness to my master.'" NIV translation
The servant prayed to the Lord and was basically asking for discernment. Instead of trusting in his own thoughts and actions, he trusted in the Lord to work in the hearts and actions of the proper woman. We may not ask the same question but we can ask for the same type of discernment.
