'Completion' in the Bible

Now at the completion of the burnt offerings, the king and all who were present with him bowed down and worshiped.

in the first year of his reign, I, Daniel, observed in the books the number of the years which was revealed as the word of the Lord to Jeremiah the prophet for the completion of the desolations of Jerusalem, namely, seventy years.

Then Paul took the men, and the next day, purifying himself along with them, went into the temple giving notice of the completion of the days of purification, until the sacrifice was offered for each one of them.

But now finish doing it also, so that just as there was the readiness to desire it, so there may be also the completion of it by your ability.
