Because you did not recognize the time of your visitation FROM GOD

[tonychanyt]

Berean Standard Bible, Lk 19:

44 They will level you [Jerusalem] to the ground—you and the children within your walls. They will not leave one stone on another, because you did not recognize the time of your visitation from God.

The phrase 'from God' was not in the Greek manuscript. Berean Literal Bible:

They will level you to the ground, and your children within you, and will not leave a stone upon a stone within you, because you did not know the season of your visitation.

Strong's Greek: 1984. ἐπισκοπή (episkopé) — 4 Occurrences

BDAG:
① the act of watching over with special ref. to being present, visitation, of divine activity

G1984-visitation often carried divine connotations in biblical usage, but the text itself didn't explicitly state "from God." This is an example of explicative addition, where translators add words to make the implicit meaning clear to modern readers.
