Gen 8:4–5: the ark rested on the mountains of Ararat

Says וַתָּנַח הַתֵּבָה, "and the ark rested" ("came to rest," BSB), is a Qal of nuakh, which BDB glosses "rest, settle down and remain," with עַל, "on." The day is בַּחֹדֶשׁ הַשְּׁבִיעִי בְּשִׁבְעָה־עָשָׂר יוֹם לַחֹדֶשׁ, "in the seventh month, on the seventeenth day of the month," and the place עַל הָרֵי אֲרָרָט, "on the mountains of Ararat": הָרֵי is a plural construct, so the text names a mountain region, not one peak.

Says In 8:5 וְהַמַּיִם הָיוּ הָלוֹךְ וְחָסוֹר, "and the waters were going and decreasing" ("continued to recede," BSB; BDB "waters continually diminished"), עַד הַחֹדֶשׁ הָעֲשִׂירִי, "until the tenth month"; בָּעֲשִׂירִי בְּאֶחָד לַחֹדֶשׁ, "in the tenth, on the first of the month," נִרְאוּ רָאשֵׁי הֶהָרִים, "the tops of the mountains were seen."

Implies וַתָּנַח at the ark's rest, מָנוֹחַ for the "resting place" the dove does not find (8:9), and הַנִּיחֹחַ, the "soothing" smell (8:21), share the consonants of נֹחַ, Noah: the three words fall at three turns of the story, so the sound-play is there, though the text does not comment on it.

Uncertain How the dates count. With months of thirty days, the seventeenth of the second month (7:11) to the seventeenth of the seventh is five months, the 150 days of 7:24 and 8:3; others count the 150 days from the end of the rain, or reckon a lunar calendar. No lean is taken here.
