Translation:

17. In gulps will he sip it but never well he be near swallowing it down his throat: Death will come to him from every quarter yet will he not die: and in front of him will be a chastisement unrelenting.

Notes (Tafseer)

1891. A graphic and deterrent picture, from the preaching of the earlier Prophets, of unrelieved horror of the torments of Hell. The door of escape by annihilation is also closed to them.
