Passage
The right hand of Jehovah is exalted, the right hand of Jehovah doeth valiantly.
The right hand of Jehovah is exalted, the right hand of Jehovah doeth valiantly.
Psalms 118:14 My strength and song is Jah, and he is become my salvation.
Psalms 118:15 The voice of triumph and salvation is in the tents of the righteous: the right hand of Jehovah doeth valiantly;
Psalms 118:16 The right hand of Jehovah is exalted, the right hand of Jehovah doeth valiantly.
Psalms 118:17 I shall not die, but live, and declare the works of Jah.
Psalms 118:18 Jah hath chastened me sore; but he hath not given me over unto death.
The verse centers on "right", "hand", "jehovah", "exalted", and "doeth". It is saying that the verse draws attention to "right" and "hand", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 15's "The voice of triumph and salvation is..." into verse 17's "I shall not die but live and...", so "right" and "hand" 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 "right" and "hand" with trust shaped by these words, not by a vague optimism outside the passage.
