Daniel 4:13

4:13 While I was watching in my mind’s visions on my bed,

a holy sentinel came down from heaven.

Daniel 4:23

4:23 As for the king seeing a holy sentinel coming down from heaven and saying, ‘Chop down the tree and destroy it, but leave its taproot in the ground, with a band of iron and bronze around it, surrounded by the grass of the field. Let it become damp with the dew of the sky, and let it live with the wild animals, until seven periods of time go by for him’ –

tn Aram “the visions of my head.”

tn Aram “a watcher and a holy one.” The expression is a hendiadys; so also in v. 23. This “watcher” is apparently an angel. The Greek OT (LXX) in fact has ἄγγελος (angelo", “angel”) here. Theodotion simply transliterates the Aramaic word (’ir). The term is sometimes rendered “sentinel” (NAB) or “messenger” (NIV, NLT).
