The four spirits of the heavens. Both the Septuagint and Vulgate render, "the four winds of heaven;" and this is doubtless correct. It was a familiar symbol to the Jews. The winds are often introduced in executing God's will on sinners (comp.
Psalms 104:4; Psalms 148:8; Jeremiah 49:36; Daniel 7:2). Which go forth from standing before the Lord (comp. Job 1:6; Job 2:1). The winds are supposed to be God's servants, waiting his pleasure to be sent forth on his errands.
The Septuagint and Vulgate translate, "which go forth to stand before the Lord." This denotes merely their usual obedience; but the text implies that the prophet sees them moving from their usual expectant attitude, and hastening forth to do God's commands.
