John Gill Commentary Daniel 4:20

"The tree that thou sawest, which grew, and was strong, whose height reached unto heaven, and the sight thereof to all the earth;" — Daniel 4:20 (ASV)

The tree which you saw, etc.] In these two verses is related part of the dream, which respects the flourishing estate of Nebuchadnezzar and his kingdom; (See Gill on Daniel 4:10), (See Gill on Daniel 4:11), (See Gill on Daniel 4:12).
