Charles H. Spurgeon on Psalms 110:7

He shall drink of the brook, etc. He describeth the passion of Christ and his glory. "In the way", saith he, that is, in his life while he is in this misery, "he shall drink out of the brook, "that is, he shall suffer and be overcome. For to drink out of the cup is to suffer: but to drink out of the brook, is to be altogether full of trouble, to be vexed and tormented and utterly to be overwhelmed with a strong stream of troubles. Thus was it in David's mind to declare the passion of Christ. Afterward he saith, "therefore shall he lift up the head". After the passion followeth the glory, with the resurrection and ascension. Paul, (Php 2:8) speaketh of both, and saith: "Christ humbled himself, and became obedient unto death, even the death of the cross. Wherefore God hath exalted him, and given him a name which is above every name", etc. Myles Coverdale, 1487-1568.
