Mark 11:4

11:4 So they went and found a colt tied at a door, outside in the street, and untied it.

Mark 13:29

13:29 So also you, when you see these things happening, know that he is near, right at the door.

tn Here καί (kai) has been translated as “so” to indicate the implied result of previous action(s) in the narrative.

tn The verb γινώσκετε (ginwskete, “know”) can be parsed as either present indicative or present imperative. In this context the imperative fits better, since the movement is from analogy (trees and seasons) to the future (the signs of the coming of the kingdom) and since the emphasis is on preparation for this event.
