Mark 14:40

Then He came back again and found His disciples still asleep, because they had not been able to keep their eyes open at all.

Mark 9:33-34

Then Jesus and His disciples came to Capernaum [Note: This city on the northwest shore of Lake Galilee had become sort of a headquarters for Jesus when He was in this region]. When He [and His disciples] entered a house He asked them, "What were you discussing on the way here?"

Romans 3:19

Now we [all] know that everything the law says applies to those who are under [obligation to obey] that law, [Note: Here "the law" appears to refer to the Old Testament Scriptures generally, since Psalms and Isaiah are quoted. See verses 10-18]. This is so that the mouth of every objector may be stopped [i.e., from making excuses for his sin], and thereby bring the entire world under God's judgment [i.e., both Jews and Gentiles].
