Contradiction with Psalm 27:10
This verse suggests that even if one's parents forsake them, the Lord will take them in, implying human abandonment is possible, which contrasts with the assurance given in Isaiah 49:15 that a mother would not forget her child.
Psalm 27:10: When my father and my mother forsake me, then the LORD will take me up. [take...: Heb. gather me]
Contradiction with Matthew 10:35-36
These verses indicate that familial relationships can turn adversarial, potentially leading to a mother being against her child, which is contrary to the assertion in Isaiah 49:15 that a mother will not forget her child.
Matthew 10:35-36: For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law.
Contradiction with Ezekiel 16:45
This verse portrays the mother as someone who has abandoned her children, directly contradicting the notion in Isaiah 49:15 that a mother will not forget her child.
Ezekiel 16:45: Thou [art] thy mother's daughter, that lotheth her husband and her children; and thou [art] the sister of thy sisters, which lothed their husbands and their children: your mother [was] an Hittite, and your father an Amorite.
Contradiction with Job 39:16
This verse describes how an ostrich disregards its young, highlighting that some mothers in nature indeed forget their offspring, which conflicts with the certainty expressed in Isaiah 49:15.
Job 39:16: She is hardened against her young ones, as though [they were] not hers: her labour is in vain without fear;
Paradox #1
The potential contradiction in Isaiah 49:15 could be the idea of comparing divine love to human love, which is imperfect. While a mother might sometimes forget her child, the verse promises that God's love is constant and unchanging. This could be seen as contradictory if one questions the existence of suffering and neglect in the world, as it challenges the notion of an ever-caring divine presence.
