Exodus 19:1
19:1 In the {a} third month, when the children of Israel were
     gone forth out of the land of Egypt, the same {b} day came
     they [into] the wilderness of Sinai.

     (a) Which was in the beginning of the month of Sivan,
         containing part of May and part of June.
     (b) That they departed from Rephidim.

Exodus 19:3
19:3 And Moses went up unto God, and the LORD called unto him
     out of the mountain, saying, Thus shalt thou say to the
     house of {c} Jacob, and tell the children of Israel;

     (c) God called Jacob, Israel: therefore the house of Jacob
         and the people of Israel signify God's people.

Exodus 19:4
19:4 Ye have seen what I did unto the Egyptians, and [how] I
     bare you on {d} eagles' wings, and brought you unto myself.

     (d) For the eagle by flying high, is out of danger, and by
         carrying her birds on her wings rather than in her
         talons declares her love.

Exodus 19:10
19:10 And the LORD said unto Moses, Go unto the people, and {e}
      sanctify them to day and to morrow, and let them wash
      their clothes,

      (e) Teach them to be pure in heart, as they show
          themselves outwardly clean by washing.

Exodus 19:15
19:15 And he said unto the people, Be ready against the third
      day: come not at [your] {f} wives.

      (f) But give yourselves to prayer and abstinence, that you
          may at this time attend only upon the Lord,
          1 Corinthians 7:5.

Exodus 19:18
19:18 And mount Sinai was altogether on a smoke, because the
      LORD descended upon it in fire: and the smoke thereof
      ascended as the smoke of a furnace, and the whole mount
      {g} quaked greatly.

      (g) God used these fearful signs, that his law would be
          held in greater reverence, and his majesty even more
          feared.

Exodus 19:19
19:19 And when the voice of the trumpet sounded long, and waxed
      louder and louder, Moses spake, and God answered him by a
      {h} voice.

      (h) He gave authority to Moses by plain words, that the
          people might understand him.

Exodus 19:24
19:24 And the LORD said unto him, Away, get thee down, and thou
      shalt come up, thou, and Aaron with thee: but let not the
      {i} priests and the people break through to come up unto
      the LORD, lest he break forth upon them.

      (i) Neither dignity nor multitude have authority to pass
          the bounds that God's word prescribes.
