When we read about crucifixion, there it is written that they did not break his legs and reference to Psalms 34:20

he protects all his bones, not one of them will be broken.

If we read the Psalms 34, David is saying about the goodness of God. How come this verse is associated with Jesus? There are more verses like this which are associated with Christ but they fit in the context from where they are taken from.
