Contradiction with Exodus 34:7
Explains that God will "by no means clear the guilty," suggesting a lack of mercy contrary to Psalms 103:8's depiction of mercy.
Exodus 34:7: Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear [the guilty]; visiting the iniquity of the fathers upon the children, and upon the children's children, unto the third and to the fourth [generation].
Contradiction with Nahum 1:2
Describes God as jealous and vengeful, which contradicts the merciful and slow to anger aspect of Psalms 103:8.
Nahum 1:2: God [is] jealous, and the LORD revengeth; the LORD revengeth, and [is] furious; the LORD will take vengeance on his adversaries, and he reserveth [wrath] for his enemies. [God...: or, The LORD is a jealous God, and a revenger, etc] [is furious: Heb. that hath fury]
Contradiction with Joshua 24:19
States that God is a jealous and unforgiving God, contrasting with the forgiving nature mentioned in Psalms 103:8.
Joshua 24:19: And Joshua said unto the people, Ye cannot serve the LORD: for he [is] an holy God; he [is] a jealous God; he will not forgive your transgressions nor your sins. [holy God: Heb. holy Gods]
Contradiction with Romans 11:22
Illustrates both the severity and goodness of God, highlighting the harsher side inconsistent with Psalms 103:8.
Romans 11:22: Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in [his] goodness: otherwise thou also shalt be cut off.
Contradiction with Deuteronomy 9:8
Describes God's anger against the Israelites, conflicting with the slowness to anger mentioned in Psalms 103:8.
Deuteronomy 9:8: Also in Horeb ye provoked the LORD to wrath, so that the LORD was angry with you to have destroyed you.
Paradox #1
Psalms 103:8 describes God as compassionate and forgiving. A contradiction or conflict could arise when considering other parts of the Bible where God is depicted as punishing or enacting harsh judgments. This could seem inconsistent with the idea of a consistently loving and merciful nature.
