In a religious context, you might want to look for a case where an event happened and then a person prayed asking for the event to happen differently, and then it turned out that the event had in fact happened as the prayer requested. I can't think of any Biblical events where the Bible makes this kind of event clear.
In one example, based on all available evidence, a person dies. The person is wrapped up in a sheet and put in a tomb, and the tomb seems to stink from the rot. The person's relatives are really sad and pray that the person recovers miraculously or didn't really die. Then it turns out that the person is calling from the tomb. In that case, we don't know if
(A) the person really died and then resurrected, or
(B) only seemed to be dead and then recovered, or
(C) the person really died and then God changed the past and the person's death was removed. Option (C) would be the Mandela effect.
In the Bible, we have the story of Lazarus being raised by Jesus, and the Bible presents the event as Option (A), because Lazarus' raising serves as a prefigurement of Jesus' resurrection.
However, one could also imagine a scenario that fits into Option C because God is outside time and beyond time. Theoretically, it seems that God could change the past in response to a current day prayer. However, I can't think of any cases where the Bible mentions this happening directly.
The Victoria Dispatch article seems to give examples where people misremembered something that happened in the Bible's narrative (eg. misremembering Eve's fruit as specifically an apple), rather than a clear specific case where the Mandela effect occurred. (

The Deconverted Man article is like that too, describing cases where people misremember what's in the Bible (like misremembering Isa 11 as being about a lion and a lamb), rather than the past actually having changed according to the Bible. (

In the story of Jonah, God gave Jonah a prediction that NIneveh would be destroyed. Jonah then warned Nineveh, Nineveh repented, and God spared Nineveh.
-- In one explanation, you could imagine that (A) Jonah was living on a timeline where Nineveh would get destroyed, but then due to Nineveh's repentence, God changed the events on the timeline, so that Nineveh would no longer get destroyed. If somehow you were standing at a point in the "original timeline" after the destruction of Nineven, and then watched God change Nineveh's fate, you would experience something like the Mandela effect.
-- In another explanation, you could imagine that (B) God knew ahead of time that Nineveh would repent and wouldn't get destroyed, but God had to put the warning in a very absolute way, so that Nineveh would get the message strongly enough. In Theory (B), the timeline was always that Nineveh would survive, but God's warning made it sound like Nineveh was going to get destroyed. My guess is that people usually think that Explanation B is what happened in the Bible.
There was an Israeli study on "Retroactive" Prayer. The study found that if people prayed for the recovery of a group of people who had been sick, then the sick people were more likely to have recovered. Chronologically, what happened is that Person A is sick, Person A recovers, then person X prays that Person A recovers, without knowing that Person A recovered.
The study's researchers concluded that (A) studies about the effectiveness of prayer must be garbage because retroactive prayer must be impossible. I am not ready to endorse this conclusion however. In my mind, the study actually opens the door to (B) Retroactive Prayer being possibly effective. Option (B) would also be like the Mandela effect.
