JC. I can prove that Luke 21:11 tells an important feature of the Sign that was not visible worldwide some decades ago, but recently has been coming more and more visible worldwide:
Luke 21:11 says, according to some Bible translations:
“There will be GREAT EARTHQUAKES.”
Luke 21:11 says, according to Greek Bible manuscript:
4578 5037 3173 2532 2596 5117
σεισμοί τε μεγάλοι καὶ κατὰ τόπους
SEISMOI te megaloi kai kata topous
earthquakes / storms both great and in every place
Luke 21:11, the translated Greek text says:
There will be SEISMOI both great and in every place, [compare, Mark 13:8] famines and plagues [that is, diseases like bubonic plague] there will be, both terrors [that is, things that will strike terror] and from heaven great signs [compare, Mark 8:11; Matt. 24:24; Rev. 13:13] there will be.
The literal meaning of the Greek noun 4578 seismos is “a shaking, quaking, trembling”. This word can be rendered “EARTHQUAKE, STORM”. The word seismos is rendered “STORM” in one verse in the Bible, in Matt. 8:24, which says: “A great STORM arose on the sea, so that the boat was being covered by the waves”. In other verses the word seismos is rendered “EARTHQUAKE”.
The literal meaning of the Greek verb 4579 seió is “to shake, quake, tremble”. In one verse in the Bible the word seió refers to a shaking caused by a STORM, in Rev. 6:13, which says: “SHAKEN by a great wind”. In two verses in the Bible the word seió refers to a quaking caused by an EARTHQUAKE, in Matt. 27:51, which says: “The earth QUAKED, and the rocks were split”, and in Hebr. 12:26, which says: “Yet once more I will QUAKE not only the earth but also the heaven” (compare prophecy in Joel 3:16; Rev. 6:12-17; Isa. 2:19-22 “he arises to cause the earth to tremble [quake]”). In two verses the word seió refers to OTHER shaking or quaking or trembling, in Matt. 21:10 and in Matt. 28:4.
The literal meaning of the Greek verb 4531 saleuó is “to shake, quake, tremble”. This word, too, refers to a shaking caused by a STORM in some verses (Matt. 11:7; Lu. 7:24), and to a quaking caused by an EARTHQUAKE in some verses (Acts 4:31; Acts 16:26 “the foundations of the prison were quaken”; Hebr. 12:26 “quaked the earth”; Hebr. 12:27 “the things that are quaken”, “the things not quaken”), and to OTHER shaking or quaking or trembling in some verses (Matt. 24:29; Mark 13:25; Lu. 6:38; Lu. 6:48; Lu. 21:26; Acts 2:25; Acts 17:13; 2 Thess. 2:2).
The Greek expression “te … kai” means “BOTH … AND”. And the word with kai is the more emphatic (Thayer’s Greek Lexicon, 5037 te, point number 2), in this case, words kata topous, “in every place”.
The Greek expression “kata topous” means “IN EVERY PLACE”, but it indicates a succession of things following one another, therefore, not in every place simultaneously, but “in one place after another”.
The words in Luke 21:11, “there will be SEISMOI both great and in every place”, therefore, mean that there will be:
1) “EARTHQUAKES both great and in every place”
2) “STORMS both great and in every place”
3) “SHAKING [caused by earthquakes and storms] both great and in every place”
The prophecy of Luke 21:11 is fulfilled when there is SHAKING both great and in every place, which is caused by a STORM and/or an EARTHQUAKE. That is, there is a GREAT EARTHQUAKE in one place, a GREAT STORM in another place, and maybe a STORM and an EARTHQUAKE in the third place, SHAKING, seismos, in every place.
