And they departed from the mount of the LORD three days' journey:
and the ark of the covenant of the LORD went before them in the three days' journey,
to search out a resting place for them. Numbers 10:33
Christ spent 3 days in death, only to emerge to lead us and make a way for us to the resting place of the Promised Land someday. And before Him went tthe ark of the covenant (the Law, which was contained inside). Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. Matthew 5:17 And where will His ark (containing the Law) appear right before His return? And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail. Revelation 11:19
