The curtain in the temple was an important symbol that showed that people needed to have someone speak to God for them. They could not speak to God directly because all people are sinful and God hates sin. God split the curtain to show that Jesus' people can now speak to God directly because Jesus has paid for their sins.
Both by pretending to worship Jesus ([Mark 15:19](../15/19.md)) and by pretending to speak to a king ([Mark 15:18](./16.md)), the soldiers and the Jews showed that they hated Jesus and did not believe that he was the Son of God.

This is a phrase in Aramaic. Mark transliterates its sounds by writing them using Greek letters. He then explains its meaning. (See: [[rc://en/ta/man/translate/translate-transliterate]])
