Let thy tender mercies come unto me, that I may live; for thy law is my delight.
Let thy tender mercies come unto me, that I may live; for thy law is my delight.
Psalms 119:75 I know, Jehovah, that thy Judgments are righteousness, and that in faithfulness thou hast afflicted me.
Psalms 119:76 Oh let thy loving-kindness be for my comfort, according to thy word unto thy servant.
Psalms 119:77 Let thy tender mercies come unto me, that I may live; for thy law is my delight.
Psalms 119:78 Let the proud be ashamed; for they have acted perversely towards me with falsehood: as for me, I meditate in thy precepts.
Psalms 119:79 Let those that fear thee turn unto me, and those that know thy testimonies.
The verse centers on "light", "tender", "mercies", "come", "live", and "delight". It is saying that the verse draws attention to "light" and "tender", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 76's "Oh let thy loving-kindness be for my..." into verse 78's "Let the proud be ashamed for they...", so "light" and "tender" belong inside that flow. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "light" and "tender" with trust shaped by these words, not by a vague optimism outside the passage.
