John Gill Commentary Job 40:14

"Then will I also confess of thee That thine own right hand can save thee." — Job 40:14 (ASV)

Then will I also confess to you that your own right hand
can save you . From all his enemies temporal and spiritual, and out of all evils and calamities whatever; and that he stood in no need of his help and assistance, yea, that he was a match for him, and might be allowed to contend with him;

but whereas he was not able to do the above things proposed to him, it could not be admitted that your own right hand could save him; and therefore ought quietly to submit to the sovereignty of God over him, and to all the dispensations of his providence, and be humbled under his mighty hand, since no hand but his could save him;

as no man's right hand can save him from temporal evils and enemies, and much less from spiritual ones, or with an everlasting salvation; nor any works of righteousness done by him, only the arm of the Lord has wrought salvation, and his right hand only supports and saves.

Two instances are given in this and the following chapter, the one of a land animal, the other of a sea animal, as is generally supposed; or it may be of amphibious ones, that live both on land and water.
