Numbers 6:27

That was God’s desire. And every time the priests said this blessing, it was to convey this desire of God to provide for them, and bless them, and be gracious to them, and smile upon them, and do good things to them.

That was His desire, that every time they came before, let us say, the Tabernacle, and the priests came out, the first thing they heard was “Hey, people! I want to bless you and give you peace, and be gracious to you.” He was just trying to let them know what He was willing to do for them, and how kind He wanted to be to them, and how much love He wanted to show them.

So God was telling them “I am watching over you, I favor you, I love you, and I want to give you peace.” The word here is ‘shalom’ which we think of as peace, but it is so much more than that. Keil and Delitzsch, the commentators, say “Shalom is the sum of all good which God sets, prepares, and establishes for His people.” In other words, “I want to give you everything that will give you a good life and a good future.” So He says, “I will bless them.” That is, in short, what His meaning is that these priests are to convey every time they come upon the children of Israel. God is here to bless. That is His intention. And you know what, we usually screw it up.
