They also that dwell in the utter-most parts - That is, Those who dwell in the remotest regions; far from civilized lands; far from those places where people are instructed as to the causes of the events which occur, and as to the being and character of the great God who performs these wonders. The idea is, that even they see enough of the evidences of the divine presence and power to fill their minds with awe. In other words, there are in all lands evidences of the Divine existence and might. There is enough to fill the minds of people with awe, and to make them solemn.
Are afraid - Thus the thunder, the storm, the tempest, the earthquake, the eclipse of the sun or the moon, fill the minds of barbarous nations with terror.
At thy tokens - Or signs. That is, the signs which really indicate the existence, the presence, and the power of God.
Thou makest the outgoings - The word rendered outgoings means properly a going forth, as of the rising of the sun Psalms 19:7; and then, a place of going forth, or from which anything goes forth, as a gate or door Ezekiel 42:11, or fountains from which water issues Isaiah 41:18; and hence, the east, where the sun seems to come forth from his hiding-place. The representation here is that the morning seems to come forth, or that the rays of light stream out from the east; and, in like manner, that the fading light of the evening - the twilight - seems to come from the west.
Of the morning and evening to rejoice - The allusion is to the east and the west. The sun in his rising and his setting seems to rejoice; that is, he appears happy, bright, cheerful. The margin is to sing - a poetic expression indicating exultation and joy.
