Psalm 98:1-4 and 2 Kings 5:14-17

Psalm 98:1-4
1 A Psalm of David himself. Sing to the Lord a new song, for he has performed wonders. His right hand has accomplished salvation for him, with his holy arm.
2 The Lord has made known his salvation. He has revealed his justice in the sight of the nations.
3 He has remembered his mercy and his truth toward the house of Israel. All the ends of the earth have seen the salvation of our God.
4 Sing joyfully to God, all the earth. Sing and exult, and sing psalms.
2 Kings 5:14-17
14 So he descended and washed in the Jordan seven times, in accord with the word of the man of God. And his flesh was restored, like the flesh of a little child. And he was made clean.
15 And returning to the man of God, with his entire retinue, he arrived, and stood before him, and he said: "Truly, I know there is no other God, in all the earth, except in Israel. And so I beg you to accept a blessing from your servant."
16 But he responded, "As the Lord lives, before whom I stand, I will not accept it." And though he urged him strongly, he did not agree at all.
17 And Naaman said: "As you wish. But I beg you to grant to me, your servant, that I may take from here the burden of two mules from the ground. For your servant will no longer offer holocaust or victim to other gods, except to the Lord.
