Contradiction with Isaiah 63:9
Isaiah describes the Lord Himself as the angel of His presence who saved the people, implying a direct intervention rather than sending others to walk the earth.
Isaiah 63:9: In all their affliction he was afflicted, and the angel of his presence saved them: in his love and in his pity he redeemed them; and he bare them, and carried them all the days of old.
Contradiction with Psalms 121:5-7
The Psalms describe God as a direct keeper and protector, suggesting He does not need messengers to watch over the earth.
Psalms 121:5-7: The LORD [is] thy keeper: the LORD [is] thy shade upon thy right hand.
Contradiction with Job 1:7
In Job, Satan is described as walking to and fro on the earth, in contrast to Zechariah 1:10 where it is angels tasked by God.
Job 1:7: And the LORD said unto Satan, Whence comest thou? Then Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it.
Contradiction with Hebrews 1:14
Hebrews speaks of angels as ministering spirits sent to serve those inheriting salvation, which differs from them having authority to walk to and fro on the earth.
Hebrews 1:14: Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?
Contradiction with Revelation 5:6
Revelation mentions the seven Spirits of God being sent out into all the earth, potentially implying a different set of beings tasked with oversight compared to Zechariah's vision.
Revelation 5:6: And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent forth into all the earth.
