443. 'And I heard one voice out of the four horns of the golden altar which is before God, [verse 14] saying to the sixth angel who had the trumpet' signifies a command from the Lord out of the spiritual heaven to those who would be examining and making manifest. By 'one voice is signified a Divine command; by 'the golden altar', or the altar upon which they used to offer incense, is signified the spiritual heaven (n. 277, 392); by 'the four horns' of that altar is signified the power thereof (n. 270), here the power of releasing the four angels bound at the river Euphrates, as it follows on; by 'the sixth angel who had the trumpet' is signified to those on whom the duty of examining and making manifest these things had been imposed (n. 442).
