Before entering the temple area the Jews were required to be ceremonially or ritually clean. This cleansing had to do with Jews having contact with Gentiles.
They did not go into the temple itself where only the high priest was allowed to enter. They entered the temple courtyard. Alternate translation: "went into the temple courtyard" (See: [[rc://en/ta/man/jit/figs-synecdoche]])
This can be stated in active form. Alternate translation: "they presented the animals for an offering" (See: [[rc://en/ta/man/jit/figs-activepassive]])
