As the people had honoured the Lord, they had honoured Moses. When Moses placed his honour upon Joshua, he did so in order to encourage the people’s obedience and loyalty toward Joshua. Moses wanted the same loyalty that had been directed toward him now directed toward Joshua. God’s people could have risen up against Joshua thinking that he had not accomplished enough to merit their loyalty. Yet, the people respected the fact that Moses had directly placed his own honour upon his minister Joshua. The people emphatically accepted Moses’ message as reflected by their answer to Joshua: “According as we hearkened unto Moses in all things, so will we hearken unto thee: only the LORD thy God be with thee, as he was with Moses” (Joshua 1:17).
The Bible says that “out of the abundance of the heart the mouth speaketh” (Matthew 12:34). This means that the words proceeding out of our mouths originate in our hearts. When we speak bitter words, it is because there is bitterness within our hearts. David likened bitter words to arrows that pierce the flesh (Psalm 64:3). Our words ought to be “seasoned with salt” (Colossians 4:6); instead, we often allow our words to pierce through others. We tear people down rather than building them up. Why is this? Because we have a root of bitterness growing inside that finds its way from our hearts into and out of our mouths. Those who demean others generally do so because they are bitter. Attempts to justify this behaviour are fruitless because the Lord knows the root of the problem stems from our heart.
