Last year on the 8th of April, a total eclipse of the sun moved across the entire United States from Mexico to Canada. One eyewitness described it as spectacular — bright sunshine becoming the deep indigo of twilight in the middle of the day. Even though people knew exactly what was happening, even though they knew it would only last a few minutes, it was still deeply unnerving and awe-inspiring. Now try to imagine what it must have been like for the people of Jerusalem when darkness came over the whole land — not for a few minutes, but for three hours. This was not an eclipse: it was Passover, celebrated at full moon, when the moon is on the opposite side of the earth from the sun. This was prolonged, inexplicable, supernatural darkness. And as we look at this single verse — Mark 15:33 — we discover four rich layers of Old Testament meaning converging on Calvary: concealment, curse, conquest, and condemnation.
