I have from time to time wondered just what a writing case would look like. Granted there would be no pens and pencils as we know them, and the paper would be much different. I wonder too why it was worn on the belt instead of carried like a brief case (9:2)?
Coals are used for cooking, and in this case the scene is more apt to represent an altar to God so the coals may be used for burning (and/or cooking) an offering or for purifying that which is unclean, or for destruction. This latter is probably the case here in chapter ten (v. 2).
The beings who go in any direction without turning represent the efficiency of the servants of God (10:9-14). There is no wasted energy, no thwarting their purpose. The four faces are all those of “ruling” creatures, or those dominate among others.
I commented earlier that Ezekiel seems to act out much more of his prophecies than any other prophet. It also seems that he has more visions than others, but perhaps this is just the way that he relates them. The command to prophesy (11:4) is a command by God to speak His truth. From the words he is given to prophesy it sounds as though the people in exile are no more godly than are those who remained in the land with Jeremiah.
What do you suppose the reaction of the exiles was when Ezekiel related his visions of the man with the writing case and the cherubim to them (11:24-25)?
Psalm 119: If some of the verses in this psalm seem a little “clipped” don’t forget that we are reading an acrostic. Each verse (line) in a section of eight verses begins with the same letter of the alphabet. “Salvation is far from the wicked because they do not seek Your statutes” (v. 155). The sum of Your Word is truth” (v. 160a). “I hate and despise falsehood, but I love Your Law” (v. 163). “Those who love Your Law have great peace, and nothing causes them to stumble!” (v. 165).
