Create an image that represents the scene from Revelation 7:2. An angel is ascending from the east, holding the seal of the living God. This angel is calling out forcefully to four other angels who have the power to harm the earth and sea. Instead of a modern digital style, please create this in an Old Testament biblical illustration style with detailed line art and color. The focus is on the ethereal quality of the angels, the radiant seal, and the dramatic exchange among the holy beings.
