2 Kings 17:9 The Israelites secretly did things against the Lord their God that were not right. From watchtower to fortified city they built themselves high places in all their towns.
Have you noticed how you will normally try to hide things which you know are not right?
Just because we may be able to hide something from another person, does not mean we can hide it from God!
The Israelites showed us time and again how they tried to secretly do things, but God saw through their ways and reminded them of the fact each time!
When they continued to do things wrong, God stepped up and made changes!
