Read the section from Chapter 8 of Don Quixote by Miguel de Cervantes.

They returned to the road they had set out with, leading to Puerto Lapice, and at three in the afternoon they came in sight of it. "Here, brother Sancho Panza," said Don Quixote when he saw it, "we may plunge our hands up to the elbows in what they call adventures; but observe, even shouldst thou see me in the greatest danger in the world, thou must not put a hand to thy sword in my defence, unless indeed thou perceivest that those who assail me are rabble or base folk; for in that case thou mayest very properly aid me; but if they be knights it is on no account permitted or allowed thee by the laws of knighthood to help me until thou hast been dubbed a knight."

"Most certainly, señor," replied Sancho, "your worship shall be fully obeyed in this matter; all the more as of myself I am peaceful and no friend to mixing in strife and quarrels: it is true that as regards the defence of my own person I shall not give much heed to those laws, for laws human and divine allow each one to defend himself against any assailant whatever."

"That I grant," said Don Quixote, "but in this matter of aiding me against knights thou must put a restraint upon thy natural impetuosity."

"I will do so, I promise you," answered Sancho, "and will keep this precept as carefully as Sunday."

How does the author convey that Sancho will obey Don Quixote above any laws?
