Adam Clarke on Isaiah 26:9

Have I desired thee - Forty-one MSS. of Dr. Kennicott's and many of De Rossi's, (nine ancient), and five editions read אויתיך invithicha. It is proper to note this; because the second י yod being omitted in the text, the Vulgate and many others have rendered it in the third person.

When thy judgments, etc. - It would be better to read, When thy judgments were in the earth, the inhabitants of the world have learned (למדו lamedu) righteousness. Men seldom seek God in prosperity; they are apt to rest in an earthly portion: but God in mercy embitters this by adversity; then there is a general cry after himself as our chief, solid, and only permanent good.
