6 Blessed be the Lord! For he has heard the voice of my pleas for mercy. 7 The Lord is my strength and my shield; in him my heart trusts, and I am helped; my heart exults, and with my song I give thanks to him.
The Return of the Seventy-Two
17 The seventy-two returned with joy, saying, “Lord, even the demons are subject to us in your name!” 18 And he said to them, “I saw Satan fall like lightning from heaven.19 Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you.20 Nevertheless, do not rejoice in this, that the spirits are subject to you, but rejoice that your names are written in heaven.”
13 May the God of hope fill you with all joy and peace in believing, so that by the power of the Holy Spirit you may abound in hope. (ESV)
