23:1 When you sit down to eat with a ruler,
observe carefully what  is before you,
2 and put a knife to your throat
if you are given to appetite.
3 Do not desire his delicacies,
for they are deceptive food.
4 Do not toil to acquire wealth;
be discerning enough to desist.
5 When your eyes light on it, it is gone,
for suddenly it sprouts wings,
flying like an eagle toward heaven.
6 Do not eat the bread of a man who is stingy; 
do not desire his delicacies,
7 for he is like one who is inwardly calculating. 
“Eat and drink!” he says to you,
but his heart is not with you.
8 You will vomit up the morsels that you have eaten,
and waste your pleasant words.
9 Do not speak in the hearing of a fool,
for he will despise the good sense of your words.
10 Do not move an ancient landmark
or enter the fields of the fatherless,
11 for their Redeemer is strong;
he will plead their cause against you. (ESV)
Many are the plans in the mind of a man,
but it is the purpose of the Lord that will stand.
