Let my supplication come before thee, and deliuer me according to thy promise.
Let my supplication come before thee, and deliuer me according to thy promise.
Psalms 119:168 I haue kept thy precepts and thy testimonies: for all my wayes are before thee.
Psalms 119:169 TAV. Let my complaint come before thee, O Lord, and giue me vnderstanding, according vnto thy worde.
Psalms 119:170 Let my supplication come before thee, and deliuer me according to thy promise.
Psalms 119:171 My lippes shall speake praise, when thou hast taught me thy statutes.
Psalms 119:172 My tongue shall intreate of thy word: for all thy commandements are righteous.
The verse centers on "supplication", "come", "before", "thee", "deliuer", and "promise". It is saying that the verse draws attention to "supplication" and "come", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 169's "TAV Let my complaint come before thee..." into verse 171's "My lippes shall speake praise when thou...", so "supplication" and "come" 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 "supplication" and "come" with trust shaped by these words, not by a vague optimism outside the passage.
