Why do some Bible verse teach there is 'no fear in love', but other verses seem to say the opposite?

I am referring to the following verses:
Proverbs 9:10: "The fear of the LORD is the beginning of wisdom."
Proverbs 1:7: Fear of the LORD is the foundation of true knowledge,

As contrasted with:
1 John 4.18: (Aramaic Bible in Plain English)  "There is no fear in love, but perfect love casts out fear, because fear is by suspicion, but he who fears is not grown up in love."
2 Timothy 1:7:  "For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind".

Proverbs 9:10

ESV - ¹⁰ The fear of the Lord is the beginning of wisdom, and the knowledge of the Holy One is insight.
