This psalm is an encouragement to all of us. Only the first two verses talk of David himself and the rest of the psalm is to encourage and reassure the reader. David knows that he can find comfort or encouragement by looking to the mountains and remembering the creator God.
There are many mountains mentioned in the New Testament and Jesus seems to often be climbing a mountain for a specific reason. Here He saw the crowds, and we can imagine that He needed to escape for a while. Jesus used that opportunity to teach His disciples some important things.
Abraham had had the angelic visitation that promised the son that Sarah and he had given up hoping for, and he was escorting his angelic visitors as they went on their way. The Lord revealed to Abraham that Sodom would be destroyed because of the evil that was happening there.
There are many different mountains named in the Bible, but this is the first time they are specifically mentioned. Earth in the creation story is not described as mountains and valleys, just land. But God obviously loves variety and we can imagine that the land He created was very varied.
Deer can leap on mountainsides that no person would dare to attempt. They do not even watch where their feet are landing, they just do it. Their feet are hard with hooves, protected by design on the day of creation. The last phrase here has a real spiritual meaning too.
What an encouraging decision Habakkuk makes after his debate with the Lord. As he contemplated the idea of no harvest of grapes figs or olives, he understood that for many of his culture at that time it meant no income, no food, and severe difficulty. What an example for us.
When we are facing difficulties, personal or worldwide, we need to find encouragement somewhere. We have a whole Bible full of encouragements, full of instruction and direction. There are also many other books available telling of miracles, and changed lives that God has accomplished for His people on the earth.
This short book began with a grumble reminding God of what the enemy was doing to His people. But Habakkuk has now persuaded himself that all will end well. It is always good to remember the past as an encouragement to ourselves and others that God is still on the throne.
God was fighting for His people. He still does. Maybe not in such a dramatic way as he did for Joshua. But maybe there are places where He is doing those things and we just do not hear about them. News media prefer telling of the tragedies and the disasters.
We understand that the Cushites and the Midianites were distressed and in anguish as they saw that the Israelites approaching. The next sentence is surely referring to when they crossed the Sea on dry land, then watched as the sea returned to its place and all the Egyptians were drowned!
