ותאמר שתה, “she said: ‘drink!’” This is the version of Eliezer when he recounted what had happened at the well. Actually, for the sake of accuracy, he should have repeated Rivkah’s exact words which had been “drink my lord!” The reason he did not repeat that version in the house of Bethuel was one of etiquette. [I believe Eliezer, who was a slave, did not want to repeat that he had been addressed as “my lord.” Ed.]
