as Sarah obeyed Abraham, calling him lord, whose children you now are, if you do well, and are not put in fear by any terror.
Sarah called Abraham "lord." The word (kurios) is variously translated as lord, master, owner, sir. It was a title of respect addressed to a father or a husband or a master. In doing so, Sarah manifested an attitude of continuous subordination and is held up as an example by the Holy Spirit Himself.
