“They established before them the Word of His signs,

Wonders in the land of Ham.”

(Psalm 105:27)

We have already noted the reference to Egypt as a portion of the land that was given to the sons of Ham (see verse 23 above). Once again, the psalmist uses this ancient reference to break of the language (and perhaps to add a certain degree of consonance with the first clause in this verse). We will not dwell on the specific miracles performed just yet, as the psalmist will do so in the following verses. It should be noted, though, that these miracles are referred to as “signs” in the text — both words, אוֹת (‘oth) and מוֹפֵת (mopheth) carry similar connotations — and these signs are referred to as “signs of His Word.”

Signs, of course, authenticate the messenger, in this case Moses and Aaron. How was Pharaoh to know that these men represented the God of creation? They worked signs and wonders that could not be repeated or undone by Pharaoh’s own magicians. Yet, the sign does not testify to the greatness of the man (men cannot do these things), they testify to the greatness of the God who sent these men. And miracles testify to the Word of the God who sent them. 

Sometimes people wonder why there are no miraculous works done today. For instance, why doesn’t God send a prophet to the White House and demand the people repent or there will be plague and famine let loose. The answer to this is that God’s Word has been finally and completely revealed. There is nothing to add to it nor can anything be taken away from it. Thus, the need for authenticating miracles has ceased and thus they are no more.
