Note 1 topic: grammar-connect-words-phrases

הֵ֤ן יַעְצֹ֣ר בַּ⁠מַּ֣יִם וְ⁠יִבָ֑שׁוּ וִֽ֝⁠ישַׁלְּחֵ֗⁠ם וְ⁠יַ֖הַפְכוּ אָֽרֶץ

if withholds in/on/at/with,waters and,dry_up and,sends_~_out,them and,overwhelm land

In both of these instances, Job is using the word and to introduce what happens under the condition he is describing. If it would be helpful to your readers, you could indicate this in your translation. Alternate translation: “if he withholds the waters, then they dry up; if he sends them out, then they overthrow the land”

Note 2 topic: figures-of-speech / metaphor

וְ⁠יַ֖הַפְכוּ אָֽרֶץ

and,overwhelm land

Job is speaking as if the waters would literally overthrow the land or turn it upside down. He means that the waters would completely cover the land so that there would be no land any more. If it would be clearer in your language, you could state the meaning plainly. Alternate translation: “and they completely flood the land”
