Genesis 31:7 is Jacob's earlier report to his wives about the same wage changes he now recounts to Laban.

In Genesis 31:38, Jacob emphasizes his careful stewardship, which complements his report of mistreatment in wages here.

Genesis 31:15 reveals why Laban acted this way — he saw Jacob and Leah/Rachel as outsiders to exploit, not family. His 'ten times' of wage-changing was consistent with treating them as foreigners.

Genesis 29:18-30 details the deception in marriage that set the stage for the prolonged service Jacob summarizes here.

In Genesis 30:33-40, Jacob's clever livestock breeding illustrates how he prospered despite Laban's changes in wages.

Genesis 29:30 details the additional service for Rachel, which Jacob references in his 20-year summary.

In Genesis 29:21, Jacob requests his wife after the first service period, which is part of the 20 years he summarizes in 31:41.

Hosea 12:12 directly recounts this episode — 'there Israel served for a wife, and for a wife he guarded sheep' — citing Jacob's labor for Laban as part of Israel's history.
