to lead or take away: to conduct a person or thing from one place to another, often under compulsion
ἀπάγω joins the everyday verb for leading or bringing, ἄγω, to a prefix meaning "away," so its plain sense is to lead someone or something off from where they are to somewhere else. The picture is of conducting, marching, or drawing a person along, with the one leading in control.
In the Gospels it is almost a fixed word of the Passion. Jesus is "led away" from one authority to the next: to the high priest, to Pilate, and finally out to be crucified. The same verb covers the whole grim procession, so following it through the trial scenes traces the path from arrest to cross.
Away from that setting the word is quieter. A farmer unties his ox and leads it off to water. A road is said to "lead" to destruction or to life, the path itself carrying the traveler to its end. And once it turns inward: before they knew Christ, Paul reminds the Corinthians, they were "carried away" to voiceless idols, swept along into worship they did not choose, close to what πλανάω names when it speaks of being deceived.
