Ishbi-benob  is a picture of our attackers.

2 Samuel 21:
^{16 Then Ishbi-benob, who was among the descendants of the giant, the weight of whose spear was three hundred shekels of bronze in weight, was girded with a new sword, and he intended to kill David.}17 But Abishai the son of Zeruiah helped him, and struck the Philistine and killed him.

OUR CRITICS

Ishbibenob is a symbol of our critics.
2 Samuel 21:16Then Ishbi-Benob, who was one of the sons of the giant, the weight of whose bronze spear was three hundred shekels, who was bearing a new sword, thought he could kill David.
17But Abishai the son of Zeruiah came to his aid, and struck the Philistine and killed him.
1) He didn't understand old age. Older experienced Christians can't be stopped:
Psalm 92: 13 Those who are planted in the house of the LORD Shall flourish in the courts of our God.
14 They shall still bear fruit in old age; They shall be fresh and flourishing,
Proverbs 16:31 The silver-haired head is a crown of glory, If it is found in the way of righteousness.
Isaiah 46:4 Even to your old age, I am He, And even to gray hairs I will carry you! I have made, and I will bear; Even I will carry, and will deliver you.
2) HE DIDN'T UNDERSTAND TEACHING
Titus 2:3 the older women likewise, that they be reverent in behavior, not slanderers, not given to much wine, teachers of good things ---
2 Timothy 2:2 And the things that you have heard from me among many witnesses, commit these to faithful men who will be able to teach others also.
3) HE SHOULD NOT HAVE USED A SWORD, WHICH PICTURES THE WORD OF GOD
Romans 14:4 Who are you to judge another's servant? To his own master he stands or falls. Indeed, he will be made to stand, for God is able to make him stand.
James 4:12 There is one Lawgiver, who is able to save and to destroy. Who are you to judge another?
4) HE SHOULD HAVE USED A BOW, WHICH PICTURES PERSONAL ATTACKS
Psalm 64:3 Who sharpen their tongue like a sword, And bend their bows to shoot their arrows --- bitter words,
4 That they may shoot in secret at the blameless; Suddenly they shoot at him and do not fear.
Notice that they pretend that their evil words are "like a sword." They are able to fake Godliness in their slander.
Psalm 11:2 For look! The wicked bend their bow, They make ready their arrow on the string, That they may shoot secretly at the upright in heart.
1 Timothy 4:10-11 For to this end we both labor and suffer reproach, because we trust in the living God, who is the Savior of all men, especially of those who believe.
These things command and teach. Reproach is an automatic part of serving God.
5) HE DIDN'T AMOUNT TO MUCH
Nothing else is known about him. His spearhead weighed half that of Goliath. Most critics of successful Chirstians are not leading successful ministries themselves.
6) HE WASN'T WELL THOUGHT OF
His name seems to mean "The Man From Nob," The Man Who Sits," The Man Who Breathes." He was not given any "champion" titles.
