Ancient of days came - The title applied to the Father in Dan 7:13 is here applied to the Son; who is called “the everlasting Father” (Isa 9:6). The Father is never said to “come”; it is the Son who comes.
judgment was given to ... saints - Judgment includes rule; “kingdom” in the end of this verse (1Co 6:2; Rev 1:6; Rev 5:10; Rev 20:4). Christ first receives “judgment” and the “kingdom,” then the saints with Him (Dan 7:13, Dan 7:14).
