'Offering' in the Bible

And he stared at him and became terrified [and] said, "What is [it], Lord?" And he said to him, "Your prayers and your charitable deeds have gone up for a memorial offering before God.

And [although] they said these [things], [only] with difficulty did they dissuade the crowds from offering sacrifice to them.

Then Paul took along the men on the next day, [and] [after he] had purified himself together with them, he entered into the temple [courts], announcing the completion of the days of purification until {the time} the offering would be presented on behalf of each one of them.
