Psalms 146:9
The LORD preserveth the strangers; he relieveth the fatherless and widow: but the way of the wicked he turneth upside down. The LORD preserveth the strangers; he relieveth the fatherless and widow: but the way of the wicked he turneth upside down.
The Lord preserves strangers and relieves the fatherless and widow, while He turns the way of the wicked upside down to overthrow it and bring it to ruin. This means God Himself does justice for the fatherless and widow and loves the stranger by giving him food and clothing. This care for the vulnerable and judgment of the wicked is part of His righteous rule, in contrast to human counsel and power. Its requirement stands in perfect agreement with the command to love God with all the heart and the neighbor as self. His justice and care for vulnerable people stand as a standard for human decisions and keep those who act under His supervision from unprincipled conduct.
The verse requires relieving a poor brother, stranger, or sojourner so he may live, taking no usury or increase, ruling without rigor, owing nothing but love, and doing all business on principles of justice and equity without partiality and without hypocrisy. Oppression of the poor is actual robbery that human courts may not punish but God marks and will in no case tolerate, and He condemns injustice and fraud wherever schemes withhold money due or deprive any person of his right, for the cries of reapers kept back by fraud enter the ears of the Lord. The verse's concern for widows and the fatherless underscores the church's obligation to care for and support widows. The verse gives large encouragement for every tempted soul to depend on Him in all personal wants, with thank offerings flowing from grateful hearts and with talking faith and practicing faith and never dishonoring God by unbelief or by a harsh spirit.
