What does Daniel 6:19 mean?

Had Darius rejected the idea of Daniel's God, he would not have been anxious (Daniel 6:18). There would have been no urge to hurry if he was assured that he'd find Daniel's remains at the lions' den (Daniel 6:10–15). Instead, his respect for Daniel (Daniel 6:1–3) and faint hope in what he knows of the Lord of Israel (Daniel 6:16) makes this moment tense. Darius might have been thinking about the miraculous deliverance of Daniel's three friends from Nebuchadnezzar's fiery furnace (Daniel 3:24–26).

Many aspects of Daniel's story foreshadow the experience of Jesus Christ. Centuries later, a group of women went to Jesus' tomb at early dawn, expecting to embalm Jesus' body. They had no hope of finding anything except a corpse. Of course, King Darius, like the women at Jesus' tomb, was about to be delightfully surprised (Daniel 6:21–22; Matthew 28:1–6).
