In verses 14 & 15 of Psalm 59 David says of the pernicious, intimidating behaviour of his enemies:
14 And at evening they return,
They growl like a dog,
And go all around the city.
15 They wander up and down for food,
And howl if they are not satisfied.
In contrast he then describes what he will do in verse 16:
16 But I will sing of Your power;
Yes, I will sing aloud of Your mercy in the morning;
For You have been my defense
And refuge in the day of my trouble.
While his enemies growled like dogs and howled when not satisfied, he would sing, focusing on God’s power, mercy, goodness and help in his life.
When the enemy attacks us, he is intimidating and menacing like dogs growling and howling. If we do what David did, respond by singing, be it out loud or in our heart and spirit, singing about God, His wonderful attributes and goodness to us, that will silence the “dogs”.
Singing about God will silence the growling dogs.
