Job 35:13

35:13 Surely it is an empty cry ¹  – God does not hear it;

the Almighty does not take notice of it.

Job 37:4

37:4 After that a voice roars;

he thunders with an exalted voice,

and he does not hold back his lightning bolts ² 

when his voice is heard.

[35:13]  ¹ tn Heb “surely – vanity, he does not hear.” The cry is an empty cry, not a prayer to God. Dhorme translates it, “It is a pure waste of words.”

[37:4]  ² tn The verb simply has the pronominal suffix, “them.” The idea must be that when God brings in all the thunderings he does not hold back his lightning bolts either.
