After speaking to them, Jesus was lifted up, and a cloud took him out of their sight (Acts 1:9). Two men in white robes said he would come in the same way they saw him go into heaven (Acts 1:10–11).
In Acts 1:9–11, Jesus finishes speaking, and the followers watch him be taken upward until a cloud hides him from view. As they keep staring into the sky, two figures in white suddenly stand near them and address them directly. This scene follows Jesus’ final instructions and promises just before his departure (Acts 1:6–8), so it functions as a transition between Jesus’ direct presence and the next phase of the story.
Acts 1:9–11 presents Jesus’ departure as a real event witnessed by his followers: they see him taken upward, then a cloud blocks their view. The story stresses what they observe and what they are told afterward (textual claims: the ascent, the cloud, their continued staring, the sudden appearance of two men in white, and the promise of return).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Acts 1:9, then read the surrounding section so the answer stays connected to the passage's flow.
9When he had said these things, as they were looking, he was taken up, and a cloud received him out of their sight.
