Deuteronomy 26:19
17 Today you have declared the Lord to be your God, and that you will walk in his ways, keep his statutes, commandments, and ordinances, and obey him. 18 And today the Lord has declared you to be his special people (as he already promised you) so you may keep all his commandments. 19 Then he will elevate you above all the nations he has made and you will receive praise, fame, and honor. You will be a people holy to the Lord your God, as he has said.
Zephaniah 3:20
18 “As for those who grieve because they cannot attend the festivals—I took them away from you; they became tribute and were a source of shame to you. 19 Look, at that time I will deal with those who mistreated you. I will rescue the lame sheep and gather together the scattered sheep. I will take away their humiliation and make the whole earth admire and respect them. 20 At that time I will lead you—at the time I gather you together. Be sure of this! I will make all the nations of the earth respect and admire you when you see me restore you,” says the Lord.
Notes and References
"... Finally, Robertson compares 3:19 and 3:20 ‘And I shall set them for a praise and for a name’ and ‘For I shall set you for a name and for praise among all peoples of the earth’ with Deuteronomy 26:19 ‘And to set you high above all the nations which he has made for a praise and for a name’. It is possible that the resemblances to the book of Deuteronomy stem from the fact that the book of the law of Moses had recently been rediscovered under the reign of Josiah and was the center of religious interest at the time of Zephaniah. The fact that there is a backdrop of Deuteronomical thought to Zephaniah in these two chapters contributes considerably to the coherence of the book, linking the first and third chapters, as the audience would have been able to fill in the linguistic gaps from their prior knowledge of the overall context ..."
