Genesis 8:3-4

8:3 The waters kept receding steadily ¹  from the earth, so that they ²  had gone down ³  by the end of the 150 days. 8:4 On the seventeenth day of the seventh month, the ark came to rest on one of the mountains of Ararat. ⁴ 

¹ tn The construction combines a Qal preterite from שׁוּב (shuv) with its infinitive absolute to indicate continuous action. The infinitive absolute from הָלָךְ (halakh) is included for emphasis: “the waters returned…going and returning.”

² tn Heb “the waters.” The pronoun (“they”) has been employed in the translation for stylistic reasons.

³ tn The vav (ו) consecutive with the preterite here describes the consequence of the preceding action.

⁴ tn Heb “on the mountains of Ararat.” Obviously a boat (even one as large as the ark) cannot rest on multiple mountains. Perhaps (1) the preposition should be translated “among,” or (2) the plural “mountains” should be understood in the sense of “mountain range” (see E. A. Speiser, Genesis [AB], 53). A more probable option (3) is that the plural indicates an indefinite singular, translated “one of the mountains” (see GKC 400 §124.o).
