Genesis 8:3

3 The waters kept receding steadily ^{▼▼ 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.”} from the earth, so that they ^{▼▼ Heb “the waters.” The pronoun (“they”) has been employed in the translation for stylistic reasons.} had gone down ^{▼▼ The vav (ו) consecutive with the preterite here describes the consequence of the preceding action.} by the end of the 150 days.
