Daniel 10:10-11

The "man" who touched Daniel and who proceeded to speak to him may have been the same one the prophet saw in the vision (Daniel 10:5-6). Walvoord held, correctly I think, that the person in Daniel 10:5-6 was God, but the person in Daniel 10:10-21 was an angel. [Note: Ibid., pp. 243, 245.] The angel described Daniel as a man of high esteem (cf. Daniel 9:23; Daniel 10:19). We know that Daniel enjoyed a good reputation among his contemporaries, but this title probably reflects God’s estimate of him. The Hebrew words (’ish hemudot) literally mean "man of preciousness." Daniel was precious to God, not only because he was one of God’s chosen people, but also because God had been precious to him.

". . . Daniel’s privileged status as one especially precious to God resulted from his complete absorption in the will and glory of the Lord to whom he had yielded his heart." [Note: Archer, "Daniel," p. 124.]

It was only appropriate for Daniel to "stand" in order to receive a message from this impressive messenger from God.
