Now Peter and John went up together into the temple at the hour of prayer, being the ninth hour. Peter and John went up together - The words επι το αυτο, which we translate together, and which are the first words in this chapter in the Greek text, we have already seen, Acts 2:47, are added by several MSS. and versions to the last verse of the preceding chapter. But they do not make so good a sense there as they do here; and should be translated, not together, which really makes no sense here, but at that time; intimating that this transaction occurred nearly about the same time that those took place which are mentioned at the close of the former chapter.
At the hour of prayer - This, as is immediately added, was the ninth hour, which answers, in a general way, to our three o'clock in the afternoon. The third hour, which was the other grand time of public prayer among the Jews, answered, in a general way, to our nine in the morning. See the note on Acts 2:15.
It appears that there were three hours of the day destined by the Jews to public prayer; perhaps they are referred to by David, Psalms 55:17 : Evening and Morning, and at Noon, will I pray and cry aloud. There are three distinct times marked in the book of the Acts. The Third hour, Acts 2:15, answering, as we have already seen, to nearly our nine o'clock in the morning; the Sixth hour, Acts 10:9, answering to about twelve with us; and the Ninth hour, mentioned in this verse, and answering to our three in the afternoon.
The rabbins believed that Abraham instituted the time of morning prayer; Isaac, that at noon; and Jacob, that of the evening: for which they quote several scriptures, which have little reference to the subject in behalf of which they are produced. Others of the rabbins, particularly Tanchum, made a more natural division. Men should pray,
1. When the sun rises;
2. when the sun has gained the meridian;
3. when the sun has set, or passed just under the horizon.
At each of these three times they required men to offer prayer to God; and I should be glad to know that every Christian in the universe observed the same rule: it is the most natural division of the day; and he who conscientiously observes these three stated times of prayer will infallibly grow in grace, and in the knowledge of Jesus Christ our Lord.
