Matthew Poole and continuators on Exodus 4:13

13 And he said, O my Lord, send, I pray thee, by the hand of him whom thou wilt send .

By one who is fitter for the work than I am. Heb. send by the hand of him whom thou wilst send, i. e. shouldest send. For the future tense oft signifies what one should do. See Gen. 20. 9. and 34. 7. Mal. 1. 6. and 2. 7. Thou usest according to thy wisdom to chuse fit instruments, and to use none but whom thou dost either find or make fit for their employment, which I am not. Others, Send by the hand of Messias, whom thou wilst certainly send, and canst not send at a fitter time nor for better work. Moses and the Prophets knew that Christ would come, but the particular time of his coming was unknown to them. See 1 Pet. 1. 11.
