Deuteronomy 26:17-18

26:17 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. 26:18 And today the Lord has declared you to be his special people (as he already promised you) so you may keep all his commandments.

Deuteronomy 5:29

5:29 If only it would really be their desire to fear me and obey ¹  all my commandments in the future, so that it may go well with them and their descendants forever.

Deuteronomy 30:16

30:16 What ²  I am commanding you today is to love the Lord your God, to walk in his ways, and to obey his commandments, his statutes, and his ordinances. Then you will live and become numerous and the Lord your God will bless you in the land which you are about to possess. ³ 

[5:29]  ¹ tn Heb “keep” (so KJV, NAB, NIV, NRSV).

[30:16]  ¹ tc A number of LXX mss insert before this verse, “if you obey the commandments of the Lord your God,” thus translating אֲשֶׁר (’asher) as “which” and the rest as “I am commanding you today, to love,” etc., “then you will live,” etc.

[30:16]  ² tn Heb “which you are going there to possess it.” This has been simplified in the translation for stylistic reasons.
