Leviticus 19:37

19:37 You must be sure to obey all my statutes and regulations. ¹  I am the Lord.’”

Psalms 103:18

103:18 to those who keep his covenant,

who are careful to obey his commands. ² 

[19:37]  ¹ tn Heb “And you shall keep all my statutes and all my regulations and you shall do them.” This appears to be a kind of verbal hendiadys, where the first verb is a modifier of the action of the second verb (see GKC 386 §120.d, although שָׁמַר [shamar, “to keep”] is not cited there; cf. Lev 22:31).

[103:18]  ² tn Heb “to those who remember his precepts to do them.”
