The relationship between God and the Israelites, referred to as Ephraim, is captured through the deeply emotional lens of a father who loves his son unconditionally. Despite the people's wrongdoings, God experiences an internal struggle, ultimately overflowing with intense mercy and compassion for them.
God reflects on whether the nation is a highly valued, important son [מצודת ציון], or a delightful child bringing joy and pleasure to a father [מצודת ציון, רש״י]. The primary approach among commentators is that these reflections illustrate the depth of God's love, treating the nation as an only child whose father fulfills his every wish [רש״י], or as a son who has never committed a wrong [רד״ק]. Another perspective distinguishes between a young child and a grown son. A father loves a young child simply for being small and charming, even when the child misbehaves. This mirrors God's love for the Israelites during their early days in Egypt. Conversely, a mature son is cherished for his good qualities and achievements, reflecting the Israelites during the era of the prophets. God holds the memories of both these periods close to His heart [מלבי״ם].
This profound love is evident in how constantly God speaks of the Israelites [רד״ק]. A person who loves someone frequently brings up their name, whereas an enemy cannot bear to mention the person they hate. The sheer frequency of God mentioning the Israelites is a testament to His deep affection [חומת אנך]. Even when God must speak words of warning or criticism, He is immediately reminded of the people's virtues because of His original, enduring love for them [מלבי״ם, רד״ק]. Additionally, the very fact that God shared His divine words with the Israelites, allowing them to study the Torah, serves as a sufficient reason to awaken His mercy [רש״י].
Because God remembers the people constantly and over a long period [מצודת ציון, מצודת דוד], a powerful emotional reaction is triggered within Him. His heart yearns and is stirred with deep compassion [מצודת ציון]. Observing the nation in their state of exile, God is overcome with longing for them [רש״י, רד״ק]. This intense emotional response culminates in a divine promise to shower them with mercy and ultimately redeem them from their exile [רד״ק].
