Ezekiel 1:28

As the appearance of the bow that is in the cloud in the day of rain, the rainbow occupying a well-defined area of brilliancy, so was the appearance of the brightness round about. Cf Revelation 4:3. This was the appearance of the likeness of the glory of the Lord, in this way Ezekiel received some impression of the exalted majesty of the Lord of the covenant, of the true God. A similar experience was accorded the prophet upon three subsequent occasions. Ezekiel 3:22; Ezekiel 8:4; Ezekiel 43:1. And when I saw it, I fell upon my face, a sinful man overcome by the glorious majesty of the holy God, and I heard the voice of one that spake. The purpose of God in granting this vision to Ezekiel was to reveal His almighty and merciful presence as the Lord and King whose power extends over the whole world, who has the strength to judge the heathen and to deliver His people, now held in shameful captivity, and let them once more enjoy the beauty of His grace. Would that the believers of all times, yea, all men, might receive the Word of the Lord with the same humility here shown by the prophet.
