Psalms 99:8

99:8 O Lord our God, you answered them.

They found you to be a forgiving God,

but also one who punished their sinful deeds. ¹ 

Psalms 106:39

106:39 They were defiled by their deeds,

and unfaithful in their actions. ² 

Ecclesiastes 7:29

7:29 This alone have I discovered: God made humankind upright,

but they have sought many evil schemes.

[99:8]  ¹ tn Heb “a God of lifting up [i.e., forgiveness] you were to them, and an avenger concerning their deeds.” The present translation reflects the traditional interpretation, which understands the last line as qualifying the preceding one. God forgave Moses and Aaron, but he also disciplined them when they sinned (cf. NIV, NRSV). Another option is to take “their deeds” as referring to harmful deeds directed against Moses and Aaron. In this case the verse may be translated, “and one who avenged attacks against them.” Still another option is to emend the participial form נֹקֵם (noqem, “an avenger”) to נֹקָם (noqam), a rare Qal participial form of נָקַה (naqah, “purify”) with a suffixed pronoun. In this case one could translate, “and one who purified them from their [sinful] deeds” (cf. NEB “and held them innocent”).

[106:39]  ² tn Heb “and they committed adultery in their actions.” This means that they were unfaithful to the Lord (see Ps 73:27).
