JMNT(i)
51 Then – it happened during the [occasion for] Him to be blessing them – He stationed [Himself] at an interval from [His] former position, away from them, and then He was progressively carried back up into the atmosphere (or: heaven; sky) again.
52 And they themselves, after doing obeisance and paying homage to Him and bowing in worship, returned into Jerusalem, with great joy.
53 Later, they were through all [times and conditions] within the Temple grounds and courts, constantly praising God, and habitually speaking good words of ease and well-being. It is so (Amen). [written circa A.D. 57-62 – Based on the critical analysis of John A.T. Robinson]
