Some blessings are thank-you notes. This one is a map. Targum Pseudo-Jonathan on Genesis 24:48 preserves the servant's second act of worship at the fountain. "And I bowed and worshipped before the Lord; and I blessed the Lord, the God of my master Abraham, who had led me in the true way to take the daughter of my master's brother for his son."
The Aramaic phrase is orach kushta — the true way, the straight road, the path without deviation. Eliezer is testifying that God did not meander him into success. God walked him there in a straight line.
This is not always how the road feels while you are on it. The servant had prayed, stood, watched, tested, waited, negotiated. From inside the day, it felt like problem-solving. From inside the retelling — and inside the bow — it looks like a line drawn by another hand.
Note the object of Eliezer's gratitude. He does not thank God for the ease of the trip, nor for the generosity of Rivekah, nor for the hospitality of Laban. He thanks God for the way. For the fact that the road itself was aimed correctly. He is praising the architecture of the providence, not merely its outcomes.
That is a prayer worth learning. At the end of a long effort, thank God not only for what you received but for the route that brought you there. The sages taught that a pious person recognizes the straight road after walking it. The straightness is the gift; the destination is its proof.
