Peter was very confused

This means that Peter was having difficulty understanding what the vision meant.

behold

The word "behold" here alerts us to pay attention to the surprising information that follows, in this case, the two men standing at the gate.

stood before the gate

"stood before the gate to the house." It is implied that this house had a wall with a gate in it to enter the property. (See: rc://en/ta/man/translate/figs-explicit)

after they had asked their way to the house

This happened before they arrived at the house. This could be stated earlier in the verse, as the UDB does.
