Zechariah 12:8 On that day the Lord will shield those who live in Jerusalem, so that the feeblest among them will be like David, and the house of David will be like God, like the angel of the Lord going before them.
Throughout our history we can see evidence of how God has always backed Israel when they have obeyed Him; but as they start to depend on their own ways they start to fall.
But during those times they have God’s backing, even the weakest of men looks strong and is able to face the enemy just as David was able to face up to so many dangers.
Trusting and believing in God has amazing and wonderful privileges and rewards; trust in Him!
