The passage in Matthew was meant for the hardened Jews who questioned Jesus' claim as the Messiah. They wanted more signs, aside from the miracles they had already witnessed, the prophecies fulfilled, etc.
https://bible.org/seriespage/19-sign-jo ... ew-1238-45The video is referencing the signs written in the heavens since the beginning. Ancient people knew how to read these signs:
Psalms 19:1
The heavens declare the glory of God;
And the firmament shows His handiwork.
Amos 5:8
He made the Pleiades and Orion;
He turns the shadow of death into morning
And makes the day dark as night;
He calls for the waters of the sea
And pours them out on the face of the earth;
The Lord is His name.
