Proverbs 6:2 if you are snared in the words of your mouth, caught in the words of your mouth,

When I read this portion of Proverb 6 I hear my father’s words; “Shut your trap.”

This line relates to the first. It does not stand alone.

Proverbs 6:3 then do this, my son, and save yourself, for you have come into the hand of your neighbor: go, hasten, and plead urgently with your neighbor.

This sounds a little like “look before you leap”.

Proverbs 20:25 It is a snare to say rashly, “It is holy,” and to reflect only after making vows.

Looking into making and keeping vows in the gospels we will find only one example.

Mark 6:22-24 English Standard Version

22 For when Herodias’s daughter came in and danced, she pleased Herod and his guests. And the king said to the girl, “Ask me for whatever you wish, and I will give it to you.” 23 And he vowed to her, “Whatever you ask me, I will give you, up to half of my kingdom.” 24 And she went out and said to her mother, “For what should I ask?” And she said, “The head of John the Baptist.”

Never make a vow without measuring the cost.

Luke 14:28 For which of you, desiring to build a tower, does not first sit down and count the cost, whether he has enough to complete it?

The example there is a tower but for us in this life with Christ it is the cost of building a new life together. He shares His plans for us and it is up to us to accept or reject those plans with a better understanding of what we are getting into, knowing what it is going to cost us.

John 12:48 The one who rejects me and does not receive my words has a judge; the word that I have spoken will judge him on the last day.

In summary, trust in the Lord, not your neighbor.

Words spoken in haste are soon regretted.
