In Isaiah 19:1, the phrase 'Jehovah rides upon a light cloud, and comes into Egypt', signifies the visitation of the natural man from spiritual-natural Divine Truth, for a visitation is an examination into the quality of a man, and examination is made by means of Divine Truth. A light cloud denotes the spiritual-natural Divine Truth from which the quality of man as to his natural-self becomes evident.

909. 'Birds' means things of his understanding and 'beasts' those of his will, [both of] which belong to the internal man; and 'every creeping thing that creeps over the earth' means corresponding things of a like nature residing with his external man. This becomes clear from the meaning of 'a bird', dealt with already in 40, 776, and of 'a beast' in 45, 46, 142, 143, 246. That 'creeping thing that creeps over the earth' means corresponding things residing with the external man is clear from this. Indeed 'creeping thing that creeps' here stands in relation both to 'birds', or things of the understanding, and to 'beasts', or those of the will. The most ancient people used to call the sensory powers and the appetites of the body 'creeping things that creep' because they are indeed just like reptiles that creep along the ground. They also likened the human body to the earth or to the ground. Indeed they actually called it the earth or the ground, as in the present verse where nothing other than the external man is meant by 'the earth'.
