What do we make of statements like these?

And to the [other angels] he [God] said in mine hearing, Go ye after him through the city, and smite: let not your eye spare, neither have ye pity: Slay utterly old and young, both maids, and little children, and women: but come not near any man upon whom is the mark; and begin at my sanctuary. Then they began at the ancient men which were before the house. Ezekiel 9:5-6

Do God’s holy angels really kill people – “old and young, both maids, and little children, and women”? Does Christ truly speak the words: “These people must die, go and execute them!” Does the Hebrew word nakah (to smite) always mean “to kill”? Jesus said He glorified His Father while here upon the earth, John 17:4. However, Jesus never killed anyone while here. Did Jesus hide this part of the character of God? If executing people is part of His character, then why did He not reveal this while here on earth?

For the Son of man is not come to destroy men's lives, but to save them. Luke 9:56

Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Show us the Father? John 14:9
