By comparing Scripture with Scripture, we can see that it is legitimate to carefully probe and ponder what Daniel did when Neb. bowed to him and "worshiped" him, as follows.
1. We do read in Scripture of other people having people bow down to them and make obeisance to them. One example that was cited earlier,
Genesis 43:28 And they answered, Thy servant our father is in good health, he is yet alive. And they bowed down their heads, and made obeisance.
2. Two other examples have also been cited where something similar occurred but
with an important difference that there were statements made about the impropriety of the action:
Acts 10:25 And as Peter was coming in, Cornelius met him, and fell down at his feet, and worshipped him. 26 But Peter took him up, saying,
Stand up; I myself also am a man.
Rev 22:8 And I John saw these things, and heard them. And when I had heard and seen, I fell down to worship before the feet of the angel which shewed me these things.
9 Then saith he unto me,
See thou do it not: for I am thy fellowservant, and of thy brethren the prophets, and of them which keep the sayings of this book:
worship God.
Scripture thus present multiple instances of people bowing down to others and "worshiping" them with differing responses by the one receiving the bowing down and the "worship."
3. What Daniel accepted, however, goes beyond any of these instances because not only did someone bow to Daniel and "worship" him but also
things were offered to Daniel:
Daniel 2:46 Then the king Nebuchadnezzar fell upon his face, and worshipped Daniel, and commanded
that they should offer an oblation and sweet odours unto him.
When offerings are made to a human being, the nature of what is done would surely seem to go far beyond someone's merely bowing to him and "worshiping" him.
It may be that Daniel did not sin on this occasion, but seriously probing what he did do is fully warranted given
the uniqueness of what took place and the explicit accounts in Scripture both of another top man of God and of an angel's speaking up about the impropriety of the actions when apparently far less was done for them than what was done for Daniel.
