'Secure' in the Bible

The Lord made them secure, in fulfillment of all he had solemnly promised their ancestors. None of their enemies could resist them.

Now the Lord your God has made your fellow Israelites secure, just as he promised them. So now you may turn around and go to your homes in your own land which Moses the Lord's servant assigned to you east of the Jordan.

A long time passed after the Lord made Israel secure from all their enemies, and Joshua was very old.
