'Guarded' in the Bible

The king of Israel sent to the place about which the man of God had told him; thus he warned him, so that he guarded himself there, more than once or twice.

Then Jehoiada the priest took a chest, bored a hole in its lid, and set it beside the altar on the right side as one enters the Lord’s temple; in it the priests who guarded the threshold put all the money brought into the Lord’s temple.
