(Ps. 118:20) זֵה∞‘This’... – this is צֵרי (tzeirei), and they are ‘the two pillars of truth’... the righteous shall enter therein – this is the Righteous-One, which is ‘the sign of the covenant’ in both-of-them. It is the ḥireq. beneath tzeirei ֵ, and it is the shureq ּ – the binding (qishura) of both-of-them. [shureq ּ with the letter Vav ו is the binding of male and female].
And because of this: (Ps. 118:21) I will give thanks to You, for You have answered me, and You have been for me a salvation, – this is uttered by the Shekhinah, Who is from the aspect of the Righteous-One, a shureq ּ in relation to Her Husband – His binding.
