Psalm 8:1

לַמְנַצֵּחַ עַל־הַגִּתִּית מִזְמֹור לְדָוִד׃

Rough Word-by-word:
To/for the overseeing one upon the Gittith; [a] Psalm of/for David.

Smooth Translation:
To the leader upon the Gittith; a Psalm of David.

Notes:
For "upon the Gittith" there are some interpretive issues:
Soncino says:
Two explanations are possible, alike based upon Jewish tradition. The Targum connects the term with the city named Gath, suggesting a musical instrument or melody which had a Philistine origin. The Midrash sees a connection with Hebrew gath, 'a winepress,' hence a tune associated with vintage songs. Modern scholars favour the second alternative.

The LXX translates with τῶν ληνῶν (the wine-presses), using the plural.

לַמְנַצֵּחַ preposition and definite article with Piel participle ms from נָצַח (he oversaw) "to/for the overseeing one"

עַל־הַגִּתִּית preposition with definite article and noun fs "upon the Gittith" (Owens parses this as a feminine plural noun while BibleWorks 4 parses it as a feminine singular - see notes above.)

מִזְמֹור noun ms "[a] psalm"

לְדָוִד preposition with proper name "to/for David"

Psalm 7:18

אֹודֶה יְהוָה כְּצִדְקֹו וַאֲזַמְּרָה שֵׁם־יְהוָה עֶלְיֹון׃

Rough Word-by-word:
I will cause to thank the LORD for righteousness of him and intensely praise the name of the LORD most high.

Smooth Translation:
I will thank the LORD for his righteousness and intensely praise the name of the LORD most high.

Notes:
In Page Kelley's Biblical Hebrew on page 145 he talks about the Vav Consecutive or Vav Conversive saying:

The vav consecutive is a special form of the conjunction which can be prefixed to imperfect forms of Hebrew verbs to express the narrated past. A passage narrating consecutive events in past time will often begin with a perfect, and then be continued by a series of imperfects with vav consecutive. Because both perfects and imperfects in such a sequence are normally translated in the past tense, it is common for grammarians to refer to the vav consecutive as the "vav conversive" and to claim that it "converts" imperfect forms of the verb into perfects.
It would be simpler to say that imperfects prefixed with vav consecutives represent consecutive actions that from the reader's viewpoint took place in past time. They may be understood as either sequential ("and then") or consequential ("and so"), although it is not always possible to draw a sharp line of distinction between these two meanings, nor is it always necessary to express the distinction in translation.

Last Friday as we began looking at Proverbs 1 we noted the ת at he end of a number of infinitive constructs. I spoke with Dr. Staats about this and he told me this is just the form of some of the weak infinitive constructs and that Weingreen talks about it.

I could not find the form in Weingreen, but in Kelley on pages 180-181 he talks about Pe Vav and Pe Yod verbs and Gutturals that take this form. Also in  Pratico's grammar on pages 236-239 he also indicates this as the form for the infinitive construct of these verbs.
