As Necho, king of Egypt, was on his way to fight against Carchemish, king Josiah of Judah came out against him for battle. Necho assured Josiah that the battle did not involve Judah and that the Lord had commanded him to make haste against the house of Carchemish. In order to turn Josiah’s intervention, Necho reminded Josiah that his intervention would be meddling with the will of God. Josiah refused to listen to the warning and meddled in these matters costing him his life (2 Chronicles 35:22-24). Gamaliel, a doctor of the law, expressed a similar statement when he told his peers that they should let the apostles alone lest they fight against God (Acts 5:34-39).
Murmuring is a grievous sin harmful to everyone involved or impacted. When God’s people murmur, they do so because their heart is not sufficiently focused upon the Lord. Various forms of the word murmur occur forty times in the word of God. Interestingly, the number forty throughout scripture is frequently connected to a time of testing or trial. The vast majority of these occurrences reflect people who were displeased with something the Lord was responsible for doing. Their displeasure with the Lord caused them to voice their frustrations to others. Murmuring generally manifests itself outwardly, but at its root is a heart problem (Matthew 12:34; Matthew 15:19). It comes as no surprise that the medical community uses the term murmur to describe a heart problem.
