-Day of Pentecost.(means 'count fifty'): A feast celebrated the fiftieth day after the sixteenth of Nisan, which was the second day of the feast of the Passover..American Tract Society:."By Moses the month is called Abib:.Exodus 13:4. The name Nisan is found only after the time of Ezra and the return from the captivity of Babylon."

In New Testament times, the word 'Pentecost' was used and was the time the Great Infinite One we commonly refer to as God, used to visibly give His Holy Spirit to those believers present for this one momentous occasion:.Acts chapter 2; 20:16; 1Corinthians 16:8.
.
The Day of Pentecost was one of the ancient commemorative feasts of ancient Israel, that the Old Testament refers to. 

Twelve tribes.comprised Israel at this time because Judah hadn't split off of Israel yet, thus becoming its own nation.

Seven complete weeks, i.e., forty nine days, were to be reckoned and then this feast of Pentecost in the spring of the year was held on the next day, the fiftieth day of this first month called Nisan on the Jewish sacred calendar. The western world's approximate spring time would here be April.

It is first spoken of in.Exodus 23:16 & Leviticus 23.as "the feast of harvest" and again in.Exodus 34:22.as "the feast of weeks" and also as "the day of the firstfruits" in.Numbers 28:26.

The purpose of this ancient feast of the Israelites was to commemorate the completion of the grain harvest.

-Selfishness:.A moody person is a selfish person. Selfishness has with it other negatives including degrees of dislike of others, often depending upon the selfish person's mood:.Jeremiah 4:22 "For my people is foolish, they have not known me; they are sottish.(foolish).children and they have none understanding. They are wise to do evil, but to do good they have no knowledge."

Selfishness focuses on one's own needs, desires and wants and discounts others' needs and avoids attempting to fulfill them. People have always had this problem of self centeredness:.Psalms 78:30.

Acts 17:21:.News is just the same old thing happening to different people:.Ecclesiastes 1:9 "The thing that has been, it is that which shall be and that which is done is that which shall be done. There is no new thing under the sun.".The entire Book of Ecclesiastes.has much to say about how futile life can be without a spiritual side to it.

This bizarre story was given at an awards dinner given by the American Association for Forensic Science:."On March 23, 1994, the medical examiner viewed the body of Ronald Opus and concluded that he died from a shotgun wound of the head. He had jumped from the top of a ten story building intending to commit suicide.(he left a note indicating his despondency). 

"As he fell past the ninth floor, his life was interrupted by a shotgun blast through a window, which killed him instantly. 

"Neither the shooter, nor the decedent.was aware that a safety net has been erected at the eighth floor level to protect some window washers. Opus would not have been able to complete his suicide anyway because of this.

"The fact Opus was shot on the way to certain death he believed was nine stories down, probably would not have changed his mode of death from suicide to homicide. 

"But the fact that his suicidal attempt would not have been successful caused the medical examiner to feel that he had a homicide on his hands. The room on the ninth floor whence the shotgun blast emanated was occupied by an elderly man and his wife. They were arguing and he was threatening her with the shotgun. He was so upset that when he pulled the trigger, he completely missed his wife and the pellets went through the window striking Opus.

"When one intends to kill subject A, but kills subject B in the attempt, one is guilty of the murder of subject B.

"When confronted with this charge, the old man and his wife were adamant that neither knew the shotgun was loaded. The old man said it was his long standing habit to threaten his wife with the unloaded shotgun. He had no intention to murder her. Therefore, the murder of Opus appeared to be an accident; that is, the gun had been accidentally loaded.

"The continuing investigation turned up a witness who saw the old couple's son loading the gun approximately six weeks prior to the fatal incident.

"It transpired that the old lady had cut off her son's finances and the son, knowing the propensity of the father to use the shotgun threateningly, loaded the gun with the expectation that his father would shoot his mother.

"The case now becomes one of murder on the part of the son for the death of Ronald Opus.

"There was an exquisite twist. Further investigation revealed that the son was Ronald Opus. He had become increasingly despondent over the failure of his attempt to engineer his mother's murder.(six weeks had passed). This led him to jump off the ten story building on March 23, only to be killed by a shotgun blast through the ninth story window. 

"The medical examiner closed the case as a suicide. The son had shot himself." ...courtesy of Calgary's Good Morning News.
