This morning in my devotions I read as is my custom the Proverbs for the day and was struck by this verse afresh:  Prov 10:22 "The blessing of the Lord--it makes [truly] rich, and He adds no sorrow with it [neither does toiling increase it]." AMP
 
Firstly what is the blessing?  The original word is: berakah (ber-aw-kaw'); from OT:1288; benediction; by implication prosperity: the KJV translates it - blessing, liberal, pool, present.
 
The Scriptures tell us that children are a blessing from the Lord.  I figured money was not what makes us [truly] rich.  Besides that was something we could increase by toiling.  Blessing is what will prosper and increase us.  Below are some Scriptures I discovered that speak of blessing.  If you have time for blessing read as many as you want.
 
Obedience results in blessing: Deut 11:26 "Behold, I set before you today a blessing and a curse: 27 the blessing, if you obey the commandments of the LORD your God which I command you today; 28 and the curse, if you do not obey the commandments of the LORD your God, but turn aside from the way which I command you today, to go after other gods which you have not known. NKJV
 
Righteousness comes with blessing: Ps 24:5 He shall receive blessing from the LORD, And righteousness from the God of his salvation. NKJV
 
God commands blessing Ps 133:3 It is like the dew of Hermon, Descending upon the mountains of Zion; For there the LORD commanded the blessing --
Life forevermore. NKJV
 
Upon our descendants: 2 Sam 7:29 "Now therefore, let it please You to bless the house of Your servant, that it may continue before You forever; for You, O Lord GOD, have spoken it, and with Your blessing let the house of Your servant be blessed forever." NKJV
 
Blessing is for God's people: Ps 3:8 "Salvation belongs to the LORD. Your blessing is upon Your people. "NKJV

He makes our places a blessing and causes showers of blessing: Ezek 34:26 "I will make them and the places all around My hill a blessing; and I will cause showers to come down in their season; there shall be showers of blessing."
 
There is no sorrow added and you can't increase by your own effort!
