And to Sarah he said, “Behold, I have given your brother 1,000 pieces of silver. Behold, it is for you a covering of the eyes to all that are with you. In front of all you are vindicated.” Bible see other translations

“your brother.” Abimelech here calls Abraham “your brother” as a sarcastic rebuke to both Abraham and Sarah.

“a covering of the eyes.” The 1,000 pieces of silver “covered the eyes” of the people with Sarah. The idiom and custom are difficult, but the essence is that the gift was to make it seem like no one saw what happened to Sarah, or if they saw what happened to her, they also saw that she was compensated for it, and thus she was vindicated or set right before all the people.
