Albert Barnes Commentary Numbers 14:13-17

"And Moses said unto Jehovah, Then the Egyptians will hear it; for thou broughtest up this people in thy might from among them; and they will tell it to the inhabitants of this land. They have heard that thou Jehovah art in the midst of this people; for thou Jehovah art seen face to face, and thy cloud standeth over them, and thou goest before them, in a pillar of cloud by day, and in a pillar of fire by night. Now if thou shalt kill this people as one man, then the nations which have heard the fame of thee will speak, saying, Because Jehovah was not able to bring this people into the land which he sware unto them, therefore he hath slain them in the wilderness. And now, I pray thee, let the power of the Lord be great, according as thou hast spoken, saying," — Numbers 14:13-17 (ASV)

The syntax of these verses is exceptionally broken. Just as Paul did when deeply moved, Moses also presses his arguments one upon another without pausing to ensure the grammatical precision of his expressions. He speaks here as if in immediate apprehension of an outbreak of God’s wrath, unless he could perhaps prevent it by rapidly presenting every plea to avert judgment and every form of intercession that he could call to mind at that very moment.
