I know, O Arjuna, the beings of the past, the present and the future, but no one knows Me.

I know the beings that have passed, those that are present, and those yet to come, Arjuna; but no one knows me.

Krishna says that he knows all beings, past, present and future, yet no one knows him. The verse expresses an asymmetry: the knower of all things is not an object that can be captured by ordinary knowledge. Krishna's knowledge spans all time, while human knowledge is limited to what passes before it. The verse also prepares for the following discussion of delusion, which explains why beings remain unaware of the one who knows them completely.
