Passage
This is the gate of the Lord: the righteous shall enter into it.
This is the gate of the Lord: the righteous shall enter into it.
Psalms 118:18 The Lord hath chastened me sore, but he hath not deliuered me to death.
Psalms 118:19 Open ye vnto me the gates of righteousnes, that I may goe into them, and praise the Lord.
Psalms 118:20 This is the gate of the Lord: the righteous shall enter into it.
Psalms 118:21 I will praise thee: for thou hast heard mee, and hast beene my deliuerance.
Psalms 118:22 The stone, which the builders refused, is the head of the corner.
The verse centers on "gate", "lord", "righteous", "shall", and "enter". It is saying that the verse draws attention to "gate" and "lord", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "Open ye vnto me the gates of..." into verse 21's "I will praise thee for thou hast...", so "gate" and "lord" 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 "gate" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
