"Contradictions" Regarding the Ark of the Covenant
by Dave Miller, Ph.D.How does the “20 years” reference in 1 Samuel 7:2 harmonize with the fact that the ark was not brought from Kirjath-jearim until 2 Samuel 6:4—more than 40 years later?
Even though God’s Word can be substantially communicated from one language to another, the translation process is sufficiently complex to the extent that many of the subtleties of the parent language are lost in translation. These subtleties rarely, if ever, involve matters that are critical to the central purpose of revelation. However, apparent discrepancies on minor details can surface that require a careful re-examination of the actual linguistic data of the parent language (in this case Hebrew) in order to dissolve the apparent discrepancy.
The individual clauses of 1 Samuel 7:2-3 are linked in Hebrew by “waw consecutives” that bring the statements into close logical and temporal connection. The three verbs of verse two are a continuation of the infinitive, which points to the main sentence being resumed in verse three (“and Samuel spoke”). The gist of these grammatical data is that the writer is informing us that after the ark’s capture, the people endured Philistine oppression for the next twenty years. Though all Israel “lamented after the Lord,” He allowed the Israelites to continue their suffering at the hands of the Philistines for 20 years—at which time Samuel called upon the nation to put away its idols.
First Samuel describes the final years of the period of the judges. The reliance upon the ark as a sort of mystical talisman brought swift military tragedy, precipitating yet another period of foreign oppression by Israel’s enemies due to their own apostasy. This period of Philistine preeminence went on for twenty years before the lamentations of God’s people were finally heard. At the end of the twenty years, Samuel called on them to couple their lamentations with genuine penitence (1 Samuel 7:3). When they put away their idolatry (vs. 4), they once again enjoyed the services of the judge (vs. 6), who assisted them in throwing off Philistine oppression by military defeat (vss. 10ff.).
Thus the twenty years refers—not to the total number of years that the ark remained in Kirjath-jearim—but merely to the number of years the ark was in Kirjath-jearim before the Lord chose to hear the people’s lamentations and provide them with intervention through Samuel.
