What does Daniel 6:7 mean?
Daniel's jealous enemies hated how he was deeply respected by the ruling king. Worse, they found that this respect was well deserved: Daniel left no room for any accusations of any kind (Daniel 6:1–4). The one area where these scheming politicians saw an opening was in Daniel's faith (Daniel 6:5). If they could force Daniel to choose between obedience to God and obedience to human law, it was clear he would choose his faith. The men have gathered, in a large group, to press the king to make a new law (Daniel 6:6).The advisors present what they claim is a unanimous proposal—Scripture does not indicate whether literally every one of the 120 satraps and the two other governors were on board. However, that is the way the idea is presented to the king. Certainly, Daniel would not have approved of such a law. The proposal is to outlaw prayers unless they are directed at the king, himself. The law seems flattering to Darius (Daniel 5:31), but it is really intended to target Daniel.
Violators would be punished by being placed into a pit or cave, or possibly an artificial enclosure, containing lions. These were probably captured animals used for just such purposes.
