Great Tribulation

In Christian eschatology, the Great Tribulation (Ancient Greek: θλῖψις μεγάλη, romanized: thlîpsis megálē) is a period mentioned by Jesus in the Olivet Discourse as a sign that would occur in the time of the end.

At Revelation 7:14, "the Great Tribulation" (Ancient Greek: τῆς θλῑ́ψεως τῆς μεγάλης, romanized: tês thlī́pseōs tês megálēs, lit. 'the great tribulation') is used to indicate the period spoken of by Jesus. Matthew 24: 21 and 29 uses tribulation (θλίβω) in a context denoting afflictions of those hard-pressed by siege and the calamities of war.
