My son, forget not my law; but let thine heart keep my commandments:
2 For length of days, and long life, and peace, shall they add to thee.
3 Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart:
4 So shalt thou find favour and good understanding in the sight of God and man.
5 Trust in the Lord with all thine heart; and lean not unto thine own understanding.
6 In all thy ways acknowledge him, and he shall direct thy paths.
7 Be not wise in thine own eyes: fear the Lord, and depart from evil.
8 It shall be health to thy navel, and marrow to thy bones.
9 Honour the Lord with thy substance, and with the firstfruits of all thine increase:
10 So shall thy barns be filled with plenty, and thy presses shall burst out with new wine.
11 My son, despise not the chastening of the Lord; neither be weary of his correction:
12 For whom the Lord loveth he correcteth; even as a father the son in whom he delighteth.
13 Happy is the man that findeth wisdom, and the man that getteth understanding.
14 For the merchandise of it is better than the merchandise of silver, and the gain thereof than fine gold.
15 She is more precious than rubies: and all the things thou canst desire are not to be compared unto her.
16 Length of days is in her right hand; and in her left hand riches and honour.
17 Her ways are ways of pleasantness, and all her paths are peace.
18 She is a tree of life to them that lay hold upon her: and happy is every one that retaineth her.
19 The Lord by wisdom hath founded the earth; by understanding hath he established the heavens.
20 By his knowledge the depths are broken up, and the clouds drop down the dew.
21 My son, let not them depart from thine eyes: keep sound wisdom and discretion:
22 So shall they be life unto thy soul, and grace to thy neck.
23 Then shalt thou walk in thy way safely, and thy foot shall not stumble.
24 When thou liest down, thou shalt not be afraid: yea, thou shalt lie down, and thy sleep shall be sweet.
25 Be not afraid of sudden fear, neither of the desolation of the wicked, when it cometh.
26 For the Lord shall be thy confidence, and shall keep thy foot from being taken.
27 Withhold not good from them to whom it is due, when it is in the power of thine hand to do it.
28 Say not unto thy neighbour, Go, and come again, and to morrow I will give; when thou hast it by thee.
29 Devise not evil against thy neighbour, seeing he dwelleth securely by thee.
30 Strive not with a man without cause, if he have done thee no harm.
31 Envy thou not the oppressor, and choose none of his ways.
32 For the froward is abomination to the Lord: but his secret is with the righteous.
33 The curse of the Lord is in the house of the wicked: but he blesseth the habitation of the just.
34 Surely he scorneth the scorners: but he giveth grace unto the lowly.
35 The wise shall inherit glory: but shame shall be the promotion of fools.
Public Domain KJV text from Wordproject.org
“Trust in the Lord with all your heart.” What does it mean?
A discussion of “trust” should include the fact that in the Greek language [including the Septuagint, the Greek translation of the Old Testament], the word is pistis—translated into English as trust, belief, or faith. We have different meanings, but in the original languages it’s all the same, and interchangeable. The conversation might intersect with the spectrum of proof/demonstration on the one hand, and impression/impulse at the extreme on the other hand. Evidence would be the place in the middle where reason and emotion meet. Evidence is what our faith/trust/belief must be built on.
So to the last half of the verse: "Never rely on what you think you know" (GNT). There's always a reality around the bend that we can’t see, a perspective farther than we can perceive.
For example: If we were to stretch a linear scale model (as opposed to a logarithmic scale) of the electromagnetic spectrum 3000 miles across the United States, from New York to San Francisco (before science discovered the electromagnetic spectrum is more than ten times bigger!), the width of the band that would represent white light, "the visible window," would be the width of the thickness of two sheets of notebook paper—seven one-thousandths of an inch. We see so little!
We need to trust…the One who sees the end from the beginning!
