Some translations set quotations from the Old Testament farther to the right on the page than the rest of the text. The ULB does this with the quoted material in 11:10.
After [Matthew 11:20](../../mat/11/20.md) Jesus begins to reveal information about himself and about the plans of God the Father, while hiding this information from those who reject him ([Matthew 11:25](../../mat/11/25.md)).
No one knows for sure whether the "kingdom of heaven" was present or still coming when John spoke these words. English translations often use the phrase "at hand," but these words can be difficult to translate. Other versions use the phrases "is coming near" and "has come near."
