'Spending' in the Bible

and as they were returning, after spending the full number of days, the boy Jesus stayed behind in Jerusalem. But His parents were unaware of it,

Now it happened that in these days he went away to the mountain to pray, and was spending the whole night in prayer to God.

So [throughout] the days he was teaching in the temple [courts], and [throughout] the nights he was going out [and] spending the night on the hill that is called [the Mount] of Olives.
